"But neither the law of armed conflict nor common sense would allow belligerents to hide behind the skirts of its civilians."
Remember that much celebrated tea party in, where was it, Boston? The one where none of the protagonists war uniforms or abided by the laws of armed conflict and then slipped back in to the public masses? The one where, today, the U.S. would classify them as illegal combatants and deny them access to any legal protection?
The one where the superior military, that could crush its opposition anywhere they stood and fought, couldn't defeat an army that kept slipping in to the countryside?
The one where the "evil" greater power could be demonised every time they caused collateral damage or took reprisals on the people the weaker force hid behind?
The one where the great general George Washington brilliantly used geurilla tactics to make up for never having more than 17,000 men in the field at any one time?
The one where, soon after winning its largely guerilla war, they wrote the second ammendment to their constitution to enshrine the right to that kind of combat?
The one where the larger but distant power regarded the attacks on its own holdings as terrorism - the term just wasn't widely used yet?
It's ironic that a nation formed on, and celebrating in its constitution, the principles of armed insurrection, guerilla warfare and terrorism when it was the weaker power gets its panties in such a collective bunch when people do exactly the same thing that worked so well for it back again.
Remember: If you win and you're powerful enough to write the history, it's noble. If you lose, it's evil terrorism. Until it's decided, which one it's viewed as simply depends on which side you're on.
