Why do you think the U.S. set up a Space Force? In my opinion, I think reason why is because they needed to prepare WW3 I guess. As you might have know already, WW3 could've happened but it just didn't. So I think America was just preparing for the war. Should countries spend more money on their armed forces? They definitely should, because they need to prepare for WW3 which might happen this year...
Good point. I think especially with the president we have now and the political climate, war is a real factor. Also consider that if an enemy took out the satellites we use for navigation and cell phones, it would be a huge problem. Space force protects those things.
