Liz asked... Why on earth assist with the defense of a country where your citizens get spat on ?

To attempt to bring them along to tolerance. It is beyond tough for these oppressed people, especially women. We have committed in the battle to overcome these injustices... and it's about time, no matter the justification is eradication of terrorism against our own. The present fight will widen to such places as the Sudan, where slavery is still practiced. Many will ask your question again, "Should we ?" Yes, until all are free.
