fifty years ago if you were a US citizen in a foreign nation you were nigh untouchable. Even the countries of most ill repute wouldnt dare to upset you. Arresting, imprisoning, or torturing an american meant incurring the wrath of a nation that could bankrupt your entire country by the end of the day, lock your ships in their ports, and ground your airplanes indefinitely. Push your luck hard enough and they could use that same blue-water naval power to raze your parliament, bomb your powerplants, and wipe out your airfields all before the sitting head of US state finished his coffee. That same power could send medical ships to your disasters as well as determine your elections, so Americans were always "welcome" on some level.
now in 2020 its a different tune. with The last 3 ground wars either lost or ended in stalemate, and the credit defaults during the debt ceiling brinksmanship of the Obama presidency, the US doesnt command the same Kissinger grade soft power it used to. Its failing health system and derelect leadership has promulgated a nation not of its greatest achievements, but rather a patchwork of cities of pestice each clawing for whatever meager federal scraps they can procure from an increasingly callous and indifferent leadership.
