Why does our military always stick their noses in other countries' business?

SGT (Join to see), it's not our military doing that. It's our politicians. I agree with SFC (Join to see) about our military being the best in the world. We probably all agree with that, right?

On top of that, our politicians (not just our current politicians) see themselves (us, our military) as the world's policeman. That, in my opinion, is why "we" stick our noses in other countries' business.

It has been fairly well answered.

To sum it up, the military goes wherever it is sent. And it does whatever it is told to do.

So many whys, but as soldiers we can only do our part, and let the almighty God to judge each person according to his deeds. Distraction is an enemy of cohesion and unity whether in the garrison or in the batterfield.

If the question interests you on an intellectual level, I highly recommend that you read sampling of academic policy analysis based on Carl von Clausewitz' "On War." This should open your eyes to this most basic of truths:
The military takes action only based on the commands of our civilian masters appointed over us. We're not an independent agency, but simply a component of a Department of the Executive Branch as controlled by the CiC IAW the Constitution and its judiciary interpretation.
Every thing a General says is filtered through the administration elected by the American citizens of age.

The question is not "Why does the military stick their noses into other countries's business" but "Why does America meddle with other countries?" And that is a Political Sciences questions that should not be answered by the people who execute rather than craft policy.

Because we are the most advanced, equipped and deadliest military force on the planet and everyone knows it. There is a lot of foreign policy involved but the BLUF is, if we don't stop them, someone else will have too.

We, the soldiers of the military stick our nosed into places we are ordered to by our leaders.

Until the end of WWII we didn't really "stick our noses" into anywhere, unless we had been attacked. After WWII, with the big push by Mother Russia to envelop the world in Communism we were the only country really able to stand in their way. Beyond that, we were the only ones left with enough strength to corral the aggressor nations in Europe and the Pacific...we became an occupation force as well as a relief force. One of the results of that was that countries like Germany, Japan and even an ally like Great Britain became addicted to the US money teat. So, the double edged sword of protection from Big Bad Bear along with dollar flow from Americans serving in those countries opened up the door for the rest of the world that wanted some semblance of freedom to come begging at the trough. That's where the politics have come in and caused us to be spread all over the world, when in virtually every case many would prefer to stay here in the good old USA. Might be a good question for your Congressman or Senator.

Thank you for asking. As others have already mentioned, the military goes where it is told to go, fights the enemies it is told to fight. The military serves to clean up diplomatic messes. Many are caused by America sticking its nose into places where it has no business (vital interest). Some are caused by mission creep; that is, we went there for a good purpose (as in clearing out a nest of vipers) but then hanging around to reinvent a culture in our own image. There are even occasions when private citizens have started fights that the military has had to finish. In Latin America, gringos were infamous for fomenting American-style revolutions. They were called filibusteros (Spanish for "pirate"). Interestingly, our word "filibuster" (to pirate or steal the discussion in the U.S. Senate) sprang from this.

It isn't our military who get us involved in other countries it our Government the Executive Branch and the Legislative branch and we in the military just follow the orders past down to us.

It's not the military-IT'S POLITICIANS!!!!!
