What exactly is a "responsible nation"? And I could be way wrong, but I somehow doubt that you are all that responsible for anything.
There are no such things as "friends and allies" on the national stage and "personal relationships" among politicians are about show, not substance. Every nation is generally out for themselves and the United States leads the way in that very endeavor. Our allies will "help" whenever it is either economically or politically expedient for them to do so. To think anything else is pure folly and totally ignorant of history.
Are you !@#$ing retarded? Apparently. So:
"It is our true policy to steer clear of permanent alliances with any portion of the foreign world, so far, I mean, as we are now at liberty to do it; for let me not be understood as capable of patronizing infidelity to existing engagements. I hold the maxim no less applicable to public than to private affairs that honesty is always the best policy. I repeat, therefore, let those engagements be observed in their genuine sense. But in my opinion it is unnecessary and would be unwise to extend them."
Washington also warned of the evils of the Two party system and was dead nutz about that as well.
