since it's a pretty important treaty and alliance. I"m sure Bibi not acting appropriately still has this administration in a tizzy though. Dealing with Russia and hearing the country you are negotiating with telling their "domestic audience" that your country should die seem so small compared to Israels war mongering Prime Minister. I mean it's not like Iran or Russia have disrespected the President like Bibi has.
