Don't be worrying too much yet about that. Get on with what you can this time will pass.
Who are you going to go to war with anyway, China? They couldn't get a proper war together 70 to 85 % of their military is involved in policing the people within the country at any one time. If it turned into a shooting war with any adversary it will be decided with new weapons before you me or anyone needs to get on the ground.
