On a scale, how much do you trust your fellow countrymen from the bad parts of town not to rob you? Then how much do you trust your politicians not to lie to you? Then how much do you trust other countries' politicians not to invade you? There's your answer right there. Trust only works locally throughout family and closely knit communities, but globally trust is like fiat currency, on a large global scale it is completely worthless on its own, without any higher form of enforcement through violent means to defend and enforce the relationship where the winner dictates the conditions and everyone else has to follow. Countries don't trust the US government, but they trust and use the USD because they trust the US will do everything militarily to protect it. That's as far as trust goes.
