Helping Ukraine is not only moral and ethical, it's also quite practical. It's done and will continue to do immense damage to Russia’s capability to threaten the NATO countries. It's united NATO after a time when the alliance was at its weakest point. We've even convinced Finland and Sweden to join NATO, which despite Turkey's negotiating tactics will happen eventually.

It assures other allies around the world that they can count on promises from the U.S., which prevents conflicts from breaking out elsewhere in the world, and also encourages countries to engage in trade with the U.S. As President Theodore Roosevelt once advised, "speak softly and carry a big stick." Much of U.S. power is based on our big stick. But if we refuse to use it when it's clearly justified, if we retreat into isolationism, our interests will suffer all over the world.

The U.S. has also gained military and intelligence benefits from helping Ukraine. We've learned a great deal about Russia's military capabilities. Ukraine has done great damage to those capabilities, not just by exposing its weaknesses, but also by killing many of Russia's most experienced officers and soldiers. If Russia is busy in Ukraine, it's less capable of causing trouble for the U.S. elsewhere in the world, as it has repeatedly tried to do.

The amount of money the U.S. has spent on the war in Ukraine is very small compared to its overall defense budget, and the value is greater than any other expenditure. But all of that will collapse if we weary of doing so and let Russia win. That will just prove that the way to defeat the U.S. and NATO is to be stubborn and brutal and outlast them. That's what Putin is counting on. It's very important to prove that's not true.

So yes, to some extent there's a sunk cost involved. But this is not like Iraq or Afghanistan where there's no long term solution. We have a clearly-defined goal and most of the world is on our side. We must see it through, while of course working towards a diplomatic solution as well. This is like our Cold War strategy, which worked because we sustained it with a bipartisan effort for 45 years. We can afford to sustain this effort -- and we can't afford the alternative.

And unfortunately, the bipartisanship is going to be a problem when you have dipshits like trump saying he trusts Putin more than US intelligence.
