We need withering sanctions+

So far the US response has been whimpering sanctions and threats that have not deterred Putin 

We need withering sanctions

We need to freeze Russian assets

We need to prosecute Putin and his generals for war crimes

We need to isolate Russia economically.

If Putin is not stopped now it will be a disaster as he tries to reform the Soviet union

And, if there’s much army remaining, we should be providing significant arms to Ukraine (anti-air, more antitank, heavy weapons, and consider providing air cover)
