saudis arnt the problem, israel would wipe them out faster than in the 6 day war... the problem is the overall arab army....
egypt now has m1a1's, atleast 500, egypt has been an agressor in the past, and i dobut that little worthless paper israel got for the suez will be worth anything in the future if egypt decides to invade with the help of the rest of israels neighbours...
offcourse m1a1 or T-whatever wont matter... egypt's m1a1's will be crushed by israels tanks because of the human factor of war, israel is simply better trained and more organised, but these M1A1's will cause more deaths on IDF side, which isnt good news for the poor guys who burn alive inside a tank from a sabot supplied by US...
i can understand that these military exports make good $ and help US economy, but why egypt? why give them 1.3 billion annually? do they even need it. they are the agressors in the past, and in addition egypt goes against US in the UN all the time, what makes egypt such a great allie that it should be given these weapons...
