It is a old Roman adage "Si vis pacem, para bellum" which held true for centuries

I didn’t say "go to war", I said "be willing to go to war". That makes the whole difference.

That's some Peacemaker stuff there. "I love peace, and I'd kill any amount of men, women and children to get it."

Current war for future peace.

I don't think so. Middle east war, Afghan war never brought any peace. Instead it backfired. So, I really don't like such platitudes.

I agree in a way, but I also think that in avoiding conflict, it is possible to see yourself pushed back into a corner to where a bigger conflict becomes necessary.
