i would not imagine that american bombs are going to help.
however, i think that if you let the jews operate freely, as they have been, the result will be beneficial to every actor that i'm in solidarity with, at the expense of those i oppose. i consequently would not support direct american intervention, except with the kurds, or in careful alignment with jewish strategic aims.
the problem is that the americans don't like watching. it makes them look bad in front of the russians.
