Specific incidents in which Putin's agenda was facilitated by America and the West:
Proxy invasion of South Ossetia, 2008
'Annexation' of Crimea, 2014
Russian-facilitated insurrection in Donetsk and the Donbass, 2014 to date
Abandonment of the US Kobani (Syria) airbase to the Russians in Syria, 2019.
We've (America, the EU, and the UN) been watching Putin do this stuff for years, and we've consistently failed to take action. I've never understood it...all we've done is embolden him.
When Saddam Hussein invaded Kuwait in the summer of 1990, and declared it to be a province of Iraq, the world community reacted immediately. The UN demanded he withdraw, and the United States organized and led a coalition that sent troops and materiel to the Middle East. When we had sufficient force in the region, we delivered an ultimatum, and then invaded and expelled the Iraqis from Kuwait.
The only differences I can see between Iraq in 1990 and Russia today are that Saddam didn't have nukes, and he didn't have useful idiots in the West running interference for him...
