As you might already know, Russian troops have invaded Ukraine. Although the Kremlin never officially declared war, troops are moving northwards from Crimea and southward from Belarus (which is siding with Russia).
Map of the conflict as of Feb 25 2022
The Biden Administration has implemented sanctions against Russia in response. However, he has not sent troops, nor does he plan to do so.
What do you think the US should do?
Extremely heavy sanctions on Russia and Belarus, effective immediately. Seize assets belonging to oligarchs. Sanction the oil sector.
If Europeans won't go along with gas sanctions in the middle of winter, fine. Wait until mid-April and if Russia is still in Ukraine and/or has replaced the government with a puppet state, sanction the natural gas sector then.
Cut Russia and Belarus off from Western technology. Heavy export controls on anything heading to Russia or Belarus. That also includes Russian-occupied frozen conflict zones like Crimea, Transnistria, South Ossetia, Abkhazia, and whatever pieces of Ukraine they happen to control at the moment.
Massive cyberattacks on Russian infrastructure. Shut off their cities' power grids, one at a time, to maximize the appearance of incompetence. Hack into their metro systems and **** with them. Steal as much money from their banks as possible. Try to crash the ruble. If they escalate, cut them off from SWIFT.
Make regime change in Belarus the official policy of the US government. Support pro-democracy activists in Belarus, Russia, Kazakhstan, and Ukraine.
Offer Finland and Sweden membership in NATO, if they want it.
Brain drain the shit out of Russia. Offer a green card to any Russian citizen who has a bachelor's degree in a STEM field and who can pass a background check. (Yes, that will be millions of people. Yes, I am OK with that.)
