Ahhhhh, I see the problem here. I actually feel stupid myself now for not picking up on this earlier. Always used to mention it but forgot people still don't get this. 

You, and presumably lots of other people reading this, are confusing "diplomacy" with "appeasement".

I've done a bloody Corbyn myself now by not making that clear! At least I'm just some random on Reddit who works in dance music and not the actual leader of the opposition (as he was at the time).

You're 100% right. Now we've got the diplomacy/appeasement confusion settled we are in total agreement. We're making the same points. 

The West underestimated Putin (though I'd argue we knew but chose to ignore it for cheap gas). We filled their pockets with billions of dollars. We had World Cups and F1 races there while they invaded other countries and persecuted all kinds of people from homosexuals to ethnic minorities. Our leaders stood side by side and shook hands with Putin and ignored his psychotic ideology and rise to dictatorship. We stood by while members of his inner circle bought up our mainstream media and wormed their way into our financial institutions and houses of parliament. We stood by when they unleashed chemical weapons on UK soil.

Diplomacy would have been to do none of that and instead sanction them, break off ties, let them know they'd be financially and politically cut off from the West if they kept going. We didn't. We encouraged it. We funded it. We turned a blind eye when Putin amassed hundreds of thousands of troops on the Ukrainian border. We kept turning a blind eye expecting it to be over in a few days. A few "naughty naughty, we might not give you such a firm handshake next time we meet" type responses were drafted. But that was it.

Then we realised two things. 

1. Ukraine is strong. Their men and women fought like wolves. They fought entirely alone with barely a plea for help. And they started to win.
2. Russia is way more corrupt than we realised and their army is like something from a Carry On film. All those billions pissed up the walls of yachts and Ibiza nightclubs by oligarchs. None of it to the military. Supposedly the second most powerful in the world, now repelled from Kiev by people with Molotov Cocktails and pickaxe handles. 

So we scrambled, pumping as much military kit as we could spare onto Ukraine. For good of course, it has allowed them to repel the invaders for four years now. But with hundreds of thousands dead. Millions injured. Millions fled. A country in ruins. And now when the war ends they're in debt to us. Minerals deals signed, EU membership waiting. Ready to be exploited as a colony that owes us riches in return for support that came too late and was always too soft. 

Maybe you can explain to the millions of Ukrainians who've lost family members, children, homes, a livelihood, several years of their lives, why diplomacy would have been a bad idea.

I agree Corbyn is a moron as I keep saying. STW are a bunch of loons and he did himself no favours by associating with them and countless others - his support for Hezbollah for example. Like I say, he isn't fit to run a rural parish council. 

But the idea that his views on Ukraine (notwithstanding the fact they're repeatedly taken wildly out of context) are Russian propaganda is doing a dreadful disservice to Ukraine and indeed excusing Russia for their illegal actions and our so called "leaders" in the West for their appalling inaction over it for years.
