In the late 1950s. . .

Egypt and Israel engaged in an artillery war.  My recollection is that it was mostly in 1958. 

During this period the two countries shelled each other over disputed territory, with Egypt doing most of the shelling.  It came to an end when Israel chose to use air power to bring it to an end.

I note that as I suspect that's what we're entering into now in Iraq, with Iran.  And if that's the case, a person should be somewhat concerned about the probably escalating course.  I.e., if they rocket us, we'll surely sooner or later take out the rocket sites, somehow.

Assuming we aren't ejected from Iraq, which is a very serious likelihood.  Indeed, if this develops, my guess is that it would be a probability, as no host nation wants to be rocketed repeatedly.

Of course, maybe they'll stop with their recent rocket strike. And maybe we won't retaliate for it.  But that seems unlikely.

All of which brings up why taking out a uniformed officer of an opposing nation, even where he is not supposed to be, in a targeted fashion isn't wise, no matter how problematic  he may be.
