i highly doubt that my friend. egypt is not afghanistan. look what they managed in 73 with old second-grade soviet stuff. had we not bailed out israel, they would have overran them. they did in the sinai.
again, consider what we provide the military. they are as nato as a non-nato member could be in terms of exquipment, logistics, etc.
The Israelis ended up crossing the Suez Canal and encircled Egypt's Third Army along with its Soviet advisors. If the Aswan Dam is destroyed, just the air pressure alone will move forward at several atmospheres. Then comes the flood..
Egypt had far more modern equipment than Israel did in a few scraps with Israel, and STILL managed to get their butts handed to them by Israel.
Never discount the Israeli propensity for coming up with very clever ways of defending themselves.
