I don't really feel like the nation's security has been compramised because of Obama being elected. There might be a blip in time where there is less security but that is because he's not putting the nation into even more debt by spending every last dime we do not even have on the military and military intelligence...rather on taking care of problems already on US soil that effect almost everyone right this instant. Terrorist attacks kill thousands, MAYBE potentially millions if something utterly insane happens. The problems that have been ignored in the past, not having to do with terrorist attacks definitely do kill millions every year.
The fact that a person of color who has ties to the Muslim world is in office is generally a good thing as it bridges a gap-whereas having a older southern white man, who speaks with an accent, makes borderline rediculous comments here and there, has a very questionable background in regards to his education and ability to lead, has a kind of incessant desire to publicly proclaim the US being the 'best country in the world'(generally speaking, do the biggest winners of the world go around telling everyone that they are?)...creates a larger gap and tends to breed dislike for Americans in general.
Bottom line: The overall feeling towards Americans is much better now than in the past and that makes it safer for them. Whereas hate towards them defintely does not.
Flame on.
