I don't think Israel is scary. Its just surrounded by a bunch a coward Arab countries who don't have courage to fight and defend themselves. Israel is always ready to fight while KSA KING is busy making peace deals with everyone around the world. 

For some reason Israel is supported by USA so much and reason is not clear to me. During 1973 Arab conflict with Israel, USA jumped in supplied tanks via airlift that saved Israel. It was for the first time in history that tanks were supplied via aircraft's. It's very obvious that Israel cant survive without support of USA.
