George Galloway says terrorism is a result of "Western countries invading, occupying, exploiting and degrading Muslim countries".
He continued: "And we must now defend ourselves."
During his talkRADIO show on Friday (June 23) he said the issue is "about the endless process of Western countries invading occupying, exploiting and degrading Muslim countries which creates a sense of grievance. Or, or as I have put it - maybe ten thousand times - a swamp of bitterness and hatred, in which mutates various forms of blowback.
"And one of those forms is the terrorist outrages we have been experiencing at an increasing rate across the Western world over the last nearly 20 years.
"Whilst we are fighting for different foreign policies, we must defend ourselves here at home, because the people who are being murdered by terrorists are not the politicians who are carrying out the unjust foreign policies. It’s somebody's daughter and somebody's son at a concert somewhere."
