A while back I came across interesting anecdotal evidence that John Lennon's politics may have changed radically (pun intended) in his last couple of years, according to Fred Seaman, who was his personal assistant in his last year and wrote a book about it.
According to this interview, Seaman says he talked a lot about politics with Lennon during that last year, and he claims that Lennon became deeply disenchanted with Jimmy Carter, and became pro-Reagan.
Plus see this.
I.e., there are indications that Lennon may have been going through that strange and relatively rare phenomenon, called changing your mind. Who knows, had he not been cut down so senselessly and tragically, and had he lived into our time, he may well have evolved past the insipid pacifism of his early middle years. No doubt this would have taken time, and during the initial Bush years one would not have been surprised to find him leading anti-Bush "Give Peace a Chance" rallies; but given the clips above, and given his innate genius and wit, one has reason to wonder if John may not have graduated to a deeper more nuanced appreciation for the human rights catastrophe represented by Islam, and for the affront to our intelligence represented by those among us who continue to shill for Islam long past the point of reason or decency.
