As long as there is no oppression and as long as there will be criminal less world we wont see that ending in the near future. I do feel it as a trillion dollar business,initially the US funded the so called ISIS as all the weapons used by them are provided by them and now they are fighting against them,it is like a video game ,so that the war keeps on rolling as well as the business.
