Western media are slowly admitting that shills, propagandists, and putinbots were right all along.

I'm assuming you're talking about the Munich pact? Yeah it might've been a mistake but the allies needed time to build up.

In order to attack Germany, right?

I suspect that the soviets would've invaded Germany if they hadn't been attacked first.

This is good.

It seems like all the major allied powers wanted to build up to attack Germany. The only difference was the Soviets saw fascism as an existential threat and the other major allied powers saw them as potential competition.

the [western] allies needed time to build up.

No, they didn't, unlike the Soviets who were dramatically less developed on account of starting from a war-torn semi-feudal backwater.

I suspect that the soviets would've invaded Germany if they hadn't been attacked first.

What's your point in even mentioning this? To demonstrate that you know that they weren't allies? Invading Nazi Germany is a good thing to do! Especially in the case of a Slavic country that would be subjected to genocide (as the USSR, like Poland, historically was) if they just waited for the Nazis to invade!
