It really should be just about that simple. When Kirk talks about a "Russian Red Line" regarding any NATO overtures to Ukraine he kind of ignores the fact that Putin just did EXACTLY the kind of thing that warrants that overture.
Yeah, Ukraine is corrupt. When the USSR folded into the Federation all the KGB and GRU goons started staking their claims to everything. Yeah, the US had all kinds of folks willing to help those goons out as long as they got a piece of the pie. There is no question that the US and Europeans are part of the problem here but we can't allow Russia to dictate Ukraine policy.
One name that DOESN'T come up in all this corruption talk, however, is Zelensky. The other major name that doesn't come up is Trump. If Ukraine is going to have half a shot at digging themselves out of the Post-Soviet hole they were in (with a lot of help getting there from the US), then Zelensky seems to be the guy that just might be able to get it done. To that end, he needs support. Real, material support.
Good argument. Unfortunately, a lot of people are trying to make Zelensky into poster child for corruption, even though he only entered politics a few years back. People should educate themselves on how Putin made his billions over the last 30 years or so.
