As far as my opinion is considered .... YES, he is. And, with the backing of the president of the USA and probably more than half of the members making up the Senate body. That's how much rotten to the core the once great nation has become. It can no longer distinguish good from evil and the sooner the decline and death of this entity the better it will be for the rest of the world.
Below are the first few paragraphs of a nicely put and very believable article by Thierry Meyssan. Worth a read in its entirety. I like it, but at the same time, I can't forget that Meyssan also firmly believes (at least he did a few years ago) that a missile hit the Pentagon and not a plane. After that, I tend to take everything he writes with a grain of salt ..... but this article about McCain's involvement with Abu Bakr al Baghadi the Houdini of Iraq, makes a lot of sense and years from now, if not sooner ... might have a lot of bite.
John McCain, Conductor of the "Arab Spring" and the Caliph
Everyone has noticed the contradiction of those who recently characterized the Islamic Emirate as "freedom fighters" in Syria and who are indignant today faced with its abuses in Iraq. But if that speech is incoherent in itself, it makes perfect sense in the strategic plan: the same individuals were to be presented as allies yesterday and must be as enemies today, even if they are still on orders from Washington. Thierry Meyssan reveals below US policy through the particular case of Senator John McCain, conductor of the "Arab Spring" and longtime partner of Caliph Ibrahim.
John McCain is known as the leader of the Republicans and unhappy 2008 US presidential candidate. This is, we will see, only the real part of his biography, which serves as a cover to conduct covert actions on behalf of his government.
When I was in Libya during the "Western"attack, I was able to view a report of the foreign intelligence services. It stated that, on February 4, 2011 in Cairo, NATO organized a meeting to launch the "Arab Spring" in Libya and Syria. According to this document, the meeting was chaired by John McCain. The report detailed the list of Libyan participants, whose delegation was led by the No. 2 man of the government of the day, Mahmoud Jibril, who abruptly switched sides at the entrance of the meeting to become the opposition leader in exile. I remember that, among the French delegates present, the report quoted Bernard-Henry Lévy, although officially he had never exercised functions within the French government. Many other personalities attended the symposium, including a large delegation of Syrians living abroad.
Emerging from the meeting, the mysterious Syrian Revolution 2011 Facebook account called for demonstrations outside the People’s Council (National Assembly) in Damascus on February 11. Although this Facebook account at the time claimed to have more than 40,000 followers, only a dozen people responded to its call before the flashes of photographers and hundreds of police. The demonstration dispersed peacefully and clashes only began more than a month later in Deraa. 
On February 16, 2011, a demonstration underway in Benghazi, in memory of members of the Islamic Fighting Group in Libya  massacred in 1996 in the Abu Selim prison, degenerated into shooting. The next day, a second event, this time in memory of those who died by attacking the Danish consulate during the Muhammad cartoons affair, also degenerated into shooting. At the same time, members of the Islamic Fighting Group in Libya ,coming from Egypt and coordinated by unidentified, hooded individuals, simultaneously attacked four military bases in four different cities. After three days of fighting and atrocities, the rebels launched the uprising of Cyrenaica against Tripolitania ; a terrorist attack that the western press falsely presented as a "democratic revolution" against "the regime" of Muammar el-Qaddafi.
On February 22nd, John McCain was in Lebanon. He met members of the Future Movement (the party of Saad Hariri) whom he charged to oversee the transfer of arms to Syria around the MP Okab Sakr . Then, leaving Beirut, he inspected the Syrian border and the selected villages including Ersal, which were used as a basis to back mercenaries in the war to come.
The meetings chaired by John McCain were clearly the trigger point for a long-prepared Washington plan; the plan that would have the UK and France attack Libya and Syria simultaneously, following the doctrine of "leadership from behind" and the annex of the Treaty of Lancaster House of November 2010. 
The Illegal Trip to Syria, April 2013
In May 2013, Senator John McCain made his way illegally to near Idleb in Syria via Turkey to meet with leaders of the "armed opposition". His trip was not made public until his return to Washington. 
This movement was organized by the Syrian Emergency Task Force, which, contrary to its title, is a Zionist Organization led by a Palestinian employee of AIPAC 
In photographs released at that time, one noticed the presence of Mohammad Nour, a spokesman for the Northern Storm Brigade (of the Al-Nosra Front, that is to say, al-Qaeda in Syria), who kidnapped and held 11 Lebanese Shiite pilgrims in Azaz.  Asked about his proximity to al-Qaeda kidnappers, the Senator claimed not to know Mohammad Nour who would have invited himself into this photo.
The affair made a great noise and the families of the abducted pilgrims lodged a complaint before the Lebanese judiciary against Senator McCain for complicity in kidnapping. Ultimately, an agreement was reached and the pilgrims were released.
Let’s suppose that Senator McCain had told the truth and that he was abused by Mohammad Nour. The object of his illegal trip to Syria was to meet the chiefs of staff of the Free Syrian Army. According to him, the organization was composed "exclusively of Syrians" fighting for "their freedom" against the "Alouite dictatorship” (sic). The tour organizers published this photograph to attest to the meeting.
If we can see Brigadier General Idriss Salem, head of the Free Syrian Army, one can also see Ibrahim al-Badri (foreground on the left) with whom the senator is talking. Back from the surprise trip, John McCain claimed that all those responsible for the Free Syrian Army were "moderates who can be trusted" (sic).
However, since October 4, 2011, Ibrahim al-Badri (also known as Abu Du’a) was on the list of the five terrorists most wanted by the United States (Rewards for Justice). A premium of up to $ 10 million was offered to anyone who would assist in his capture.  The next day, October 5, 2011, Ibrahim al-Badri was included in the list of the Sanctions Committee of the UN as a member of Al Qaeda. 
In addition, a month before receiving Senator McCain, Ibrahim al-Badri, known under his nom de guerre as Abu Bakr al-Baghdadi,
created the Islamic State in Iraq and the Levant (ÉIIL) – all the while still belonging to the staff of the very "moderate" Free Syrian Army. He claimed as his own the attack on the Taj and Abu Ghraib prisons in Iraq, from which he helped between 500 and 1,000 jihadists escape who then joined his organization. This attack was coordinated with other almost simultaneous operations in eight other countries. Each time, the escapees joined the jihadist organizations fighting in Syria. This case is so strange that Interpol issued a note and requested the assistance of the 190 member countries. ..........
