Supporting Ukraine isn’t in America’s interest. Stopping bankrolling random foreign wars was one thing republicans finally got right after decades of getting it wrong.
And the border proposal was a fake-out, just like Reagan’s amnesty, which was supposed to be combined with border controls but never was. The goal of the recent border legislation was to make 5,000 illegal crossings a day (5 times higher than under Obama) the “new normal.”
It is absolutely in America's interest. For less than 0.01% of the defense budget, the USA can disarm Russia as a threat for another 50 years, if not forever.
The ROI looks pretty good:
1. Bolster NATO (Sweden and Finland have joined already)
2. Bolster the EU (Ukraine and Turkey gaining membership would be interesting)
3. Revive EU self-interest in not relying on US military and cash. This directly results in less foreign random wars because more parties are stakeholders.
4. Diplomatic leverage against China. They are actively supplying manufacturing capacity for weapons to the Russians.
5. Transparency around for who is supplying who with what regarding weapons and Russia. This makes it easier to sanction people/companies that do things that are Bad For Business globally.
