What is to keep the planet safe?
Military? When we see what an army, 22 times wealthier than Iraq's, achieves in that country, we know armies are not exactly keeping the planet safe.
Armies of occupation, against the will of the occupied, have they ever been successful?
Interesting how, in order to justify its country's military adventures halfway around the globe, one needs to argue about other countries having the same intentions as their's.
To keep the planet safe is to keep it in good enough shape for the next generations to thrive on it, weather they are muslims, christians or atheists.
