i mean, how does the u.s. support ukraine without, you know, threatening or feeling or making russia feeling threatened? you re exactly right, amar a. this is a really delicate balling act and that s what putin is counting on because putin knows that nateors and the united states are not going to commit troops to ukraine s aid so the only thing we real very left is sanctions, and as you point out we impose sanctions after 2014 and the russians are still in crimea seven years later. so the question is what could you do that would really make the difference? well, you could do a few things? you could disconnect russia from the global financial system by cutting them all from the swift system, the system that basically does international transactions. could you go after the oligarchs who help fund putin. you could go after putin s own money as well. the problem is once you have done that and putin reacts, what s your next step? you always want to leave
