Make it simple, if you are a U.S. citizen, use this website to direct your comments to your elected leaders regarding how the USA should support Ukraine NOW. "The only thing necessary for the triumph of evil is for good men to do nothing."
1) Urgent maximal military supplies to allow Ukrainians to defend themselves, including Stingers, man pads, ammunition, drones
2) Urgent economic/financial/energy sanctions against all the Central Bank of Russia (CBR), Russia banks, state owned enterprises
3) Pursue war crimes of Putin, his targeting of orphanages, kindergartens and residential buildings
4) Personal sanctions broad and deep against Putin, his Cabinet members, his Duma members, his National Security Council members and all their families -- no visas, no universities, no hidden townhomes, villas, yachts
5) No use of U.S. airspace, no Aeroflot landing rights
6) Ban social media platforms from running ads or monetizing Russian state disinformation channels, remove licenses for Russian state media to operate in the USA
5) Financial aid for Ukraine to maintain its economy in the face of Russian attempts to strangle it
6) Humanitarian aid for those refugees crossing the border in search of safety and for those residents staying in Ukraine
