With a lot of munitions going to Ukraine and being used or blown up, there is very little left in Americas munition reserves to help Israel if necessary. Even if Biden were to say, Let's go save Israel, would America have enough resourses at the ready to help? I don't think so. Maybe Israel is on its own fighting this new war. And if Egypt decides to jump in and have a two front war, who will win the game of attrition? This might be the point where the Arabs have the upper hand, unless Israel uses really big boom-booms. Let's just see what happens in a couple of day from now. It will either blossom into a full fledged war or will be a small simmering pot of tit for tat missle attacks.
