but i think down the road it is really critical to being able to allow prosecutors in the international space like the icc to potentially bring prosecutions forward because what the united states can do is share this evidence that they have collected to make this legal determination with those who can actually bring forth these prosecutions for those responsible. i think the other important thing to note here is that this isn't just a determination of one thing that russia is doing in ukraine but it is talking about the widespread nature of what they're doing. the executions, the forced deportations, going after just the totality of the ukrainian civilian population. that is why it is so significant. >> and on the question of what more can the united states provide to ukraine at this pivotal moment, it has seemed that the u.s. has eventually come around to the request whether tanks or other things late. after they have waited quite sometime, maybe out of concern
