Like when he gave away Crimea with no oppostition and split up Ukraine's energy sector amongst his party cohorts kid's? Oh, wait that was Obama...
We don't own Crimea so it's not ours to "give away"
I assume you mean when Putin invaded Crimea which resulted in sactions by many countries including the US
BTW - you know TRUMP fully supports Putins agenda in both Crimea and Ukraine even though his position (Trump) is totally contrary to the stated US Policy
