I'm neither left nor right. I haven't considered my position to be either since my teens over twenty years ago, when I felt aligned with liberal left wing thinking.
And there is no qualifier here. You either against war, or you're not. You don't get to pick and choose according to your belief system. If everyone flat out refused to fight in wars then we could just shove all the politicians, bankers, and hidden power players into a ring and watch them duke out it instead. Wars can only happen, like everything else, with your approval. If they decide to enact conscription at jail or pain of death, then so be it. Let them imprison or kill everyone like the deranged entitled toddlers they really are at heart.
All of the wars from the 20th/21st century have been pointless, because they have all been contrived. You just don't know it. The British establishment is largely responsible for the majority of it, including both world wars. That's an unpalatable and disturbing truth, especially for British people who think we're the good guys, but it is true. Hitler wouldn't have come to power if it wasn't for the conditions we created by the first world war, and subsequent aftermath of it.
And nothing has changed. Guess who's behind this bullshit with Russia? Everyone points to the USA, but in actuality it is the British establishment pulling the strings. We are the masters of propaganda, of intelligence (five-eyes), masters of espionage and the dark arts.
It was MI6 and the CIA over a decade ago doing their thing in Ukraine that set the internal stage in Ukraine for what we see now, and the British establishment more generally coordinating NATO etc to create the circumstances that led Putin to do what he has done. Not that Putin himself isn't just playing a role, being a WEF young global leader of course.
You're right. It is black and white. Because it's all bullshit.
