> No country with the means to respond militarily would decline to do so. And no army in the world has ever disengaged from a conflict once casualties became asymmetric.

None of this is true. The UK did exactly this in Ireland during the IRA insurgency.

Interesting that you end your comment with flimsy justification for targeting and killing UN workers and peacekeepers, which Israel is now doing.

You basically ignored most of my comment. I never said anything about morally right, I argued from the realism of the past 20 years of counterterrorism. It leads me to think you're not responding in good faith. Like I said earlier, I have seen and am no longer willing to support wasting billions of dollars on ignoring the root of terrorism, ignoring the diplomatic means which worked with other terrorist groups (IRA, Taliban, ANC, Irgun, etc.) Maybe one day you will too
