Why only US worried about world safety?

Compare to Canada, UK, China, Russia, India, Australia, Germany, Brazil and there are many more countries that are living in their own world. They have their own laws against terrorism and immigration and seems like working. Is America too much divided nation?

US is not worried about world safety, It is worried about its own safety, Their Investments in other country, Business in other country, their Crude oil safety, Big brother Mentality because the have developed, created, many enemies before and after cold war we can have many example for it.

Cuba : Thorn in their foot they was converted as their enemies because they have a communist government which was not ready to dance to the tune of CIA

Afghan : To counter Russia,s Invasion their CIA was sole responsible to breed Tail bans by giving Weapons, Money, other Equipments and now they are used against US.

Iraq : Once US close ally during Iran Iraq war weapons and all other things was gifted to Saddam in exchange of cheap crude and same against US now.

N. Korea : The Com-mun its state which was attacked by US forces after the Korean division and by name of sanction they made many attempt to topple the Communist Govt which has led to Nuclear blast.

Pakistan : The only friend of America in past which has used US and CIA for it personal developments got all help past and present in term of Weapons, Money all other which help all extremist groups in and around the world where the US govt is def and dum on them

So US has sowed the seeds and NOW they have grown into trees and it is must and necessary for US to cut it because it is only person in the world who knows where they planted it.

We weren't before Bush. You can thank him for it.

i don't think it's that we are divided....when is the last time you heard of these countries having illegal immigrant problems? you don't because it doesn't happen...no offense to any other country, but this is "the land of the free" and alot of people have "an American dream" i've never heard of the canadian dream, the brazilian dream or the chinese dream...have you? also if you think about it, 9/11 was truly the first time in over 50 years the US has ever had a terrorist attack...prior to that the closest thing to it was pearl harbor and that wasn't out of the blue or necessarily a terrorist attack. so i think the terrorist efforts are something we are still getting used to. we've always had plans and laws in place, but never had to use them. it's like doing a fire drill....it seems useless till you need it, and we've never needed cause to worry about terrorist...we haven't done "air-raids" in years.

Did you forget that the US is the world police?

offence is best defence

The problem is that they believe that they are the policeman of the world..take your troops out of there and nobody will attack you!

they really are not, but it is a good excuse to promulgate new laws like the patriot act(s)I & II

They just want to get their business into everything and control the world.
