With the possible exception of Egypt or Saudia arabia, the former because of their M1-A1 Abrahms,t he latter because of their air force, Israel would easily wipe the floor in a military engagement with any of its nearby neighbors. Thats without our assistance anymore too. None of the governments in the area really want a war with israel yet. Given current trends, another 10 years, maybe some of the others would have a shot too, but doubtful. At any rate, militants, spies, insurgents, etc, send them in with empty pockets and no identifiable marks, and whos to say if they are soldiers or terrorists? Israel wants to keep the alert status high enough they can continue their military buildup with popular support, the surrounding countries turn a blind eye because it makes them look good without actually offending Israel, and so things continue for another thousand years.
