I get where you are coming from. In the last two decades, the USA and allies have spent trillions of dollars increasing the suffering and death in Iraq and Afghanistan, and didn't even gain much geopolitical advantage in return. A giant waste of time, money, and human life. Had we not invaded them, there might be a million more Iraqis alive today. Afghanistan would still be a failed state though.

The 2014 invasion of Ukraine was not a significant news event for me. Ukraine was weak, and the tepid response to the invasion from Ukraine and the rest of the West meant that Russia just rolled in without opposition or much drama.

Fast forward 8 years, and Ukraine has further developed its national identity and is starting to become a real democracy. The 2022 invasion was a big wake-up call for the West. We had thought that we had won the Cold War in 1992, and that our geopolitical rivals, while still warranting concern, were not a direct threat to us and our allies anymore. Nope! It turns out there is still a need for the USA to be an unrivaled global superpower, and for the rest of NATO to get its ass in gear and modernize.
