I don't know what you call it, but when repeated requests for meetings to discuss an item are ignored - that's a snub. I personally don't care that the US does or does not sanction Israeli actions. They are a sovereign nation - they can make their own decisions. Were the tables reversed Obama would be screaming bloody murder about being snubbed. It's called Diplomatic Courtesy. It seems that's lost upon Obama and you.
Israel has been a reliable ally and deserves better treatment, i.e. courtesy. Far more than the Arab nations as demonstrated by Libya and Egypt.
Per usual you let your hatred for Obama obscure the facts. Since 2009 Obama has failed to meet with Netanyahu ONLY ONCE when Netanyahu visited the US and requested a meeting. At that time, Obama was out of the country. Netanyahu has NEVER been snubbed. There was no request for a meeting this time until after Netanyahu got his shorts wadded up and saw an opportunity. Like his buddy, Mitt, he believes never let an opportunity to lie in order to influence an election decision or get your way, go to waste. It's called Diplomatic Discourtesy. It seems that's lost on Netanyahu and you.
