Two factors, probably:

• America has never had a war on our soil, a real bona-fide war anyway. Smaller town or city-sized disputes that got whitewashed and omitted from history, of course. I don't think we fully comprehend what is necessary to protect our freedom? Not apologist here either, just...that is partly why. Look at how much we constantly boast about WWII even though we just showed up late, well-rested with a bunch of guns, after almost turning Fascist ourselves.
• In America: You protest, you riot, you lose your job because you don't have enough time off available to drive 2500 miles, or the reason isn't valid based on made up rules by your employer. Then you lose your health insurance because you have no job. Then you lose your home because you can't pay the mortgage (or more these days, rent), your car on a 5 year loan is repo'd. So now your family is homeless without transportation or medical care and you're basically dead at that point.

They set the US up to make failure->death the easy fast default option unless you're a proper peasant working the fiefdom.
