No one will topple America. If America falls it falls from massive civil wars and breakup within. Not from any outside sources.
Military advantages of America:
1) Tons of land and populations vastly spread out. Too many cities (major and smaller ones) to concur as well.
2) Citizenry armed to the teeth. Prepping and distrust in authority and others is rather normal in most of America.
3) Our military has enough nukes to wipe out the entire world.
4) Any hostile invasion against us would quickly galvanize citizens across the country to take up arms and start using them against those who try to run us down. Notice that due to the massive migration the guns sales are soaring month after month, year after year. The taking up of arms has already begun….. just not the next step (because it hasn't gotten that bad)….. yet.
