Is the US really resented?

Is the U.S really resented? After my last post I got a comment that really got me thinking...Are we really resented by other countries and if so why?
The thing that really gets me wondering about this is, is it truly our responsibility as the world power to aide others? Being bestowed with this role comes great responsibility. We are obligated as the most powerful nation and prosperous to help those less fortunate than us. Many of the third world countries need our assistance and could not survive without us. With their corrupt governments, high rates of poverty, unsanitary living conditions, lack of technology and protective forces someone needs to step in and provide for them. Without our guidance the unfortunate countries might have crushed into shambles. These countries cant provide for themselves and by eliminating these issues is somewhat like preventative work, and can help eliminate issues in the future.
United...we stand strong! It is not just us who does the work but other powerful countries as well. We are not alone to help the hundreds of countries that need it. We are not standing alone on these issues, the other powers of the world need to take action along side of us. Others need to make a force alongside of us to make a difference in these shambling countries.
Resentment for the US has increased especially since the beginning of the war of terrorism. Iraqi resentment of our occupation of their country has sky-rocketed because it has gone on so long (http://www.namibian.com.na/2003/march/national/03C997B88E.html.) This could explain the high number of suicide bombings in cities and rebellions.
A comment on a blog made me put it all into perspective...our population has been exponentially growing and mainly because of immigrants. They are a huge part of the place we live in. We are not resented by all if millions are leaving their homes in other countries to come live in the U.S. Even if they dont like the way we run things here they are coming here because they know there are unlimited opportunities here and most will live a better life coming to our nation. So even if we are resented it is not the point that others will not respect us and know we are the world power. They want to have the opportunities that we have here so they come to be a part of it, regardless if they like the way we do things here or not.
The thing that we should mainly put our focus on to satisfy our citizens is the amount of money we put into foreign affairs. If we do have the responsibility to help others then we just have to monitor our expenses and figure out what is "too much." With the upcoming election next year things can change vastly. Considering the decrease in President Bush's popularity over the duration of his time in office, mainly due to Iraq War policies, the new change in leadership might alter our foreign policy ( http://progressive.org/mag_apb11150) This might cause less resentment towards our country. Although most countries should be greatful of our eagerness to help out mainly the more powerful countries who dont need our help seem to be the ones who envy us. I think this could be due to jealously of of reign over the world and our prosperity and success. The smaller nations receiving our aide temporarily should be grateful to us for helping them survive. This is not always the case, especially in Afghanistan, with our troops dominating their country there has been much resentment which has resulted in suicide bombers(http://www.rawa.org/temp/runews/2007/03/29/afghanistan-resentment-grows-against-foreign-troops.html.) Although we have done so much for the world sometimes it is not appreciated and misinterpreted as a nationalistic or imperialistic drive.
