"Clinotus, what's your point? why do we need to have military bases in any part of the eastern hemisphere...? we're in the western hemisphere."
To have military bases is an essential portion of US's foreign policy, to be able to react to world-wide disasters as soon as possible.
"Because we have the technology to kick some @ss in war, that means we should use it to protect other countries? Why can't we be a neutral country? Switzerland I has proven to be a very neutral country, they managed to stay out of WWII. Why can't we be like them?"
Which brings us to the second point, why do we interfere with other nation's actions?
Bad examples of foreign intervention in the past:
1) Vietnam
2) Bosnia
But can we really not intervene based upon just those 2 events? "Don't toss out the baby with the bathwater" as they say . . .
Why should we intervene? In a sense, because of our moral standings. Can you sit idlely aside as your neighbor beats up his wife? Can you sit there and watch as one of your neighbor another kills another? It's the guilt trip, and the belief that we can help towards the better. That is why we interfere. Sure, sometimes US interferes partially for selfish goals (establishing military bases, boosting public image, gaining some political power in other countries) but in the end if they did not have a beneficial reason the countries would not allow America to interfere in the first place.
Secondly, I don't know what era you're from, but isolationism doesn't work. As the Japanese and Chinese have tried in the 18th, 19th, and 20th centuries, isolationism leads to the country falling behind in standard technology.
The result is either all the other countries cooperate as they do today, and excel past America. Else, warfare between foreign countries will lead to slow destruction of civilization. Also, US has many important alliances and if one of them enters a war, US is also forced to enter a war. Whether you like it or not, I think it's easier to stomp out 20 small fires than to try to put out one big fire.
Please stop whining without reason. If you do attempt to counter-argue, please base it with at least a bit of reason and judgement besides using absolute statements without elaboration.
