Should Promoting Democracy Abroad Be A U.S. Priority?

Although America always wants to help other countries, I believe those countries should have their own government at their own discretion. I believe America should not intervene on other countries, just as we don't want other countries in our business.
First of all, money is a huge issue. In our current economic times, can we really afford to be sending our troops over to Iraq and other countries to "promote democracy?" The article sates that The Middle East Partnership Initiative spent just under 28 million dollars. Only about 2 million went to organizations to help them expand their work. Where is this money coming from and why are we supporting this cause? Second, we are not providing a positive example to Iraq, our current "fix." American liberalism has only caused the people "death and chaos", not positive government like we would have hoped.
The other side of the argument says that in order to keep peace and earn it back is to make democracy a global government. I couldn't disagree more. Other countries believe their form of government is best, like we believe democracy is best. In our class discussion, you told us about a foreign exchange student who was from China. When a remark was made about communist China, he backed up his country and government he believed in. Asking for one type of government is like asking for one type of religion.
America, unless it can prove it is a country with few flaws, should be concerned with government directly influencing America, not worry about what other countries believe is right.
