Ukraine is another example of US meddling in another country's internal affairs, on the other side of the world. The Minsk accords were a ruse by the West to buy time for Ukraine to prepare for conflict with Russia, former leaders of Germany and France publicly admitted it, and played Putin for a fool, because Putin actually wanted peace with the West.
Up until the start of the Russian special military operation and after, Russia tried to negotiate a peaceful resolution which the US, EU and NATO all ignored; it's well known that Ukraine and Russia had the start of a peace agreement in Turkey until Johnson met with Zelensky and Ukraine backed out of the negotiations.
Even at the start, Russia moved slowly in Ukraine, it wasn't shock and awe, it was meant to bring Ukraine to negotiations. Only after the West made it clear that they would not accept any negotiations with Russia that Putin started to take and keep territory.
The US and its' allies gave Russia only one option to preserve it's national defense, so it's the only option Russia had, and Russia took it. And when it's over, what's left of Ukraine is going to be much smaller and insignificant that it was before the conflict.
