Has the US lost much of its credibility? and is it justified?

Yes we have, and it is justified. Sadly, our nation is despised by the majority of the rest of the world, and the perception is legitimized by the policies our leaders have implemented. With all of the scandals, corruption and blatant deceptions we have experienced in our current White House, you reap what you sow. We need to change our foreign policy and initiate national reform. Our priority should be taking care of our homeland, healthcare and immigration. We should stop expanding Globally to make greater profit and invest in our own economy. We need to stop importing workers from the Middle east and Asia and employ more US workers. We also need to stop utilizing cheap foreign labor and stop importing products from the Middle east and Asia.
