Having been a army recruit in the mid 60's. Going first to Oman, then Yeman, then Veit Nam, then oman then Yemen , thenm Ireland, Ireland, Ireland, Then Yemen, Beruit, then Ireland, beruit. (Forget the next 16 years it;s all reputition in different counties). All you have is religious conflict.
In 24 years in the military and 82 active service asignments being 98% of my total career. Only one 2 week asignment was not religiously instigated.
Religion is great until it becomes radical.
I have read and understand the Koran, I fully understand Catholic, I was brought up Chappel and C of E. They are all the same once the radicals take over.
