This concept is so disingenuous. The earth is is big enough for Russian, China, and the US to coexist in peace. My country's spending should be spent in my country. Not liberating a land that has nothing to do with us.
A plane can take you or your cargo to the other side of the world in a day, missiles can go much faster than that, and communications are instantaneous. The world is still a big place but it's naive to ignore the facts of technological interconnectedness.
That's incredibly sanguine. Russia has been annexing territory and this was a gambit to take a huge chunk by force. If they had rolled over Ukraine in weeks as many predicted they'd have pointed their guns at Belarus and Georgia and all the former satellites. Acquiescing is what we did to Hitler when he wanted the Sudetenland and he was not appeased by it.
I'd also cite John Donne and say "no man is an island". Our "country" exists as an arbitrary artifact of history. If you are capable of caring about people you don't know then it shouldn't matter if they're from another state or another country.
Some countries conduct the exactly amount of war they are capable of doing, kill as many people as they have the capacity to do, until they are stopped. Russia is one of those countries.
