Egypt fought three Wars with Israel. 1948,1967 and 1973. It lost thousands of soldiers to support Balestinian Arabs. In 1967 it lost the whole of Sinai and in 1973 Israel was 100 km from Cairo with the Egyptian First Army entrapped and unable to defend Cairo. Do you truly believe that a war with Egypt would have a different result and this time they would not get the Sinai back and Israeli troops would be at the Suez Canal.
Is that your solution for Egypt?
I have been to Egypt and saw the poverty and the overcrowding and people living in cemeteries.
