I've explained that I use the term "invasion" in a completely neutral sense. Foreign military forces move in to help overthrow a de facto regime - I call that an invasion, and so do most people.

But call it something else. The point is that what Omar Kadhr is accused of cannot justifiably be called "murder". This wasn't a terrorist action, it was a military engagement carried out by American forces against people who had been identified as enemy in which there were casualties on both sides.
