Mac asked:
Is one man's terrorist really another man's freedom fighter?
Often we are searching, seeking clarity as we are told that is needed to think, let alone argue with others. I think our brains however complex seek simplicity and a great deal of modernity instructs us to think so.

Secondly, enemies and friends as history shows are not constant.

Afghanistan is a superb example. Following the Soviet invasion the USA allied with Saudi Arabia and Pakistan support the "Muj"; the Soviets exit, US support ends; Pakistan creates and supports the Taliban, after 9/11 the US wages war on the Taliban and Pakistan is a friend or enemy to the Taliban and the USA.
