I am sure that if Muslim Brotherhood succeeds in starting a war with Israel, I am sure their @$$ will get kicked and then some !
In 1973, the Egyptians completely retook the Sinai peninsula before Israel was able to counter-attack (resupplied by the US), and eventually pushed all the way back and even went across the Suez canal into Egypt proper. That was against soviet tanks.
If you noticed in the TV coverage, Egypt now has M1 Abrams tanks. Not a good thing for Israel.
