Cuba
After the Cuban Revolution of 1959, relations between the U.S. and Cuba declined substantially and were marked by tension until very recently. The U.S. initiated an embargo on Cuban goods, but friendly relations between the two countries were formally reestablished in 2015 with the opening of embassies in both Havan and Washington, D.C.
Lebanon
Pew surveys have found that, on average, 44% of Lebanese people expressed a positive opinion of the United States, while 55% expressed unfavorable views toward the country. Relations between the countries became compromised due to accusations of double standards regarding American aid to Israel against Hezbollah during the 2006 war.
