I didn't say it was a US decision. The reality is this - armed security teams are on board US flag ships, and when their ships arrive in foreign port, it is often against the law of that port state. Those individuals aren't LEO's either, however, accommodations have been reached with a number of port states.

All it takes is people responding rationally to a threat. Which is, of course, why we are in the state we're in. Rational thinking seems to be an endangered species when it comes to countering the terrorist threat.
