You've got to look a further out then this weekend.
The first thing Hamas said when they got power is that all deals with Israel are null. That is par for the course with Arabs.
Egypt and Jordan and SA are certainly threats to Israel. They (and Syria and Iran) (and likely even an Iran dominated Iraq) are the only threats. Israel can not be defeated by terror alone but by terrorists controlling those Arabs nations. Which is inevitable.
Jordan will be governed by Hamas types in the intermediate future with Egypt to follow.
Every single weapon the US sells the Arabs today has the potential to be used against Israel.
Your bald assurances that Egypt and Saudi Arabia are not threats to Israel is not reassuring.
History demonstrates otherwise. In 1948, 1956, 1967, 1969 (War of Attrition), and 1973 Egypt spearheaded aggressive wars against Israel. All that stands between them is the coldest of peace and the limited life of Hosni Mubarak in a country that is increasingly being radicalized by political Islam (Al Qaeda, Brotherhood).
We in the US, a much more powerful nation oceans away, are rightfully afraid of China who has never attacked us. Also China unlike the Islamists would be deterred by mutual distruction. But tiny Israel surrounded by hostile radicals is not in danger?
That is quite a double standard.
Granted Iran is the immediate greater threat. Nukes trump conventional. But Syria and Jordan are nothing compared to Egypt.
