Why did many Americans disapprove of giving the Panama Canal to Panama?

a.They felt like a small nation had humiliated the U.S. by forcing it to give up an important asset.
b.Panamanian rebels had seized the canal, and Carter had agreed to negotiate with them.
c.Panama was demanding that the U.S. pay higher tolls to use the canal after Panama took control of it.
d.The Panamanian people had signed a treaty in 1903 giving the U.S. permanent control over the canal.

Panama was full of anti-American riots during 1964, the Panamanians did not agree with the US control of the canal, they believed that it was an affront to the Panamanian sovereignty. In 1977 during Carter’s administration, the US and Panama signed an agreement, there were two treaties: 1) Terminated the original Treaty and created a new one giving complete control over the canal to Panama and 2) A Treaty that gave the US a right to protect the canal’s neutrality.

Many Americans did not agree with the Treaties and said that the Americans bought it, paid for it and should keep it, they believed that America had the right to the canal.
