History does repeat it's self. Wait until our manufacturing capability gets so poor that our economy can't support our military infrastructure.
It already can't support it - whole deficit is 800bln, and is greater than your defense budget.
Many of the people from Chernobyl are still waiting for the Ukraine government to make good on basic human resources and some are moving back to Chernobyl even thought it is a death sentence because they have no other place to go.
They will be waiting for Ukrainian government forever. Not happening, period. It's a wonder there is still such a thing as "Ukraine government".
Are you ready to support military readiness at the expense of basic human services like Russia and company do? With our diminishing economic health from moving manufacturing overseas, at some point we will have to choose. Military might or funding basic human services.
I think you are at the point where deep cuts, down to the bare bones, are needed. Across the board, both to military and welfare. Military - all you can afford really is just enough to keep the borders intact. No NATO, no military bases abroad, no allies defense, no invasions anywhere. Welfare - basic services only (food, shelter, clothing) at basic levels. Such as smallest place in cheapest-to-live areas. No "I want to live there and not here", no other "want" things. If a low-income Grandma is lucky to have grown middle-class kids, the kids need to be asked to chip in for the Grandma or take her home, not food stamps or Section 8.
China didn't necessarily say right now. All they have to do is just wait as our economy and ability to support our military readiness degrades and they will be able to just walk in and overtake us.
It will be by far worse. In the event you run down your economy and weaken your statehood, China, Russia, Europe, Canada - everyone will be pasturing here for something useful and interesting. Such as innovations, projects, teams of professionals, technologies, companies, assets. And the rest - will be just left here to degrade and rust. Nobody will want to take the responsibility for the territory and poor people that will be left here.
