Ukraine

The world and the nations are a lot more complicated than that. I get the desire to be so reductionist, but the West is a complex mix of countries with a lot of competing agendas who have committed to coming to the aid and defense of their partner nations. None of them can make decisions in a vacuum, and as much as they've mostly supported Ukraine, you have to remember that support is not unlimited or reckless.

I don't think cowardice is an accurate description. They're part of a coalition and while you might perceive selfishness, I perceive that they're wanting to preserve their partnership. The actions we take as a nation affect other member nations, so our actions with Ukraine need to be measured carefully.
Call it what you want. When the war first started the complications of supplying Ukraine with armored vehicles were used to explain why no one wanted to supply those weapons systems. It was explained to me that my simplistic idea about doing these things just showed that I was ignorant of the facts.

The fact is we're slow rolling our aid. If we, meaning the US, had supplied Ukraine with ATACMS, HIMARS, Bradleys, Patriots etc and F-16s (I know F16s require more training and logistics) right off the bat the situation in Ukraine would look a lot different. Our NATO allies look to us to take the lead, as evidenced by the reluctance to provide armor till we announced we were going to send Abrams. We didn't even have to send them, all we had to do is signal that it was okay and suddenly everybody who them was sending MBTs.

Remember that Biden said that we had to temper our aid with a view toward relations with Russia after the war. In other words we still want to do business with them. We also stopped all US aid for 6 months at crucial time in the war.

They've oblitirated whole major cities, killed tens of thousands of of cilillians, targeted hospitals, schools, crowded shopping centers and civillian infrastructure. Now they're bringing Koreans. So Putin has no restraints whatever but we're still placing crippling restrictions Ukraine. And the further away from Russia you get the less enthusiastic the support (with some exceptions). Germany sends a lot financial support but not much else, France is more concerned with their former colonies in Africa, the UK tries but their military (like Germany) has regressed to the point that they couldn't defend themselves from an attack if they had to.

After three years we're finally starting to see F16s become a factor. Imagine if we had started training and building a logistical support chain a soon as Ukraine asked (begged) for it. How many lives and assets could have been saved. How much more successful would Ukraines counter offense have been if they were properly equipped? And now that they've accumulated some long range capabilities we won't let them use them effectively. Meanwhile whole cities are being reduced to rubble.

I stand by my reductionist statement.
