I have no sympathy with him. The man sees the West as the enemy. His actions are quite clear about that - from the IRA, the Cold War to the Falklands. He is about as far-left as it is possible to go in mainstream British politics. He is a dangerous man, who has some extremely disgusting bed-fellows.
It is usually a good idea to ensure that you are on the opposing side of Corbyn in any major national dilemma.
The man’s an atrocity of a politician.
Peter Hitchens thinks that Corbyn is pretty good on foreign policy but has noted his leftness on the IRA who are by tradition Marxist.
Nigel Farage says that when he campaigned for Brexit he had the DUP and even a Sinn Fein member with him on occasions but nowadays Sinn Fein signs the song of corporatists and globalists in favor of the EU.
