I don't think you have to be concerned about this part
"By backing out now, we not only show that were giving up/showing our incompitance"
There have been globs of posts along the lines of "fuck the world, who cares what they think", "fuck the UN, we don't need them", "fuck every other country, we don't need em or want em".
So really, there is no need to be concerned about what anyone else thinks in the world, as the rest of the world is irrelevant.
Just keep in the front of your thought process that everyone else doesn't matter at all, and then you won't have to be concerned about what anyone thinks. It worked for going in there in the first place, so just use the same approach on exit.
