In order to carry on with an activity that is frowned upon by a lot of people, it is necessary to do it under cover. American support of Israeli settlements is one of those things needing cover. America supports the settlements in many ways. One of the most direct ways is by giving Israel billions of dollars on a regular basis which they can use for their "defense", freeing up Israeli money to provide subsidies and support for settlements. Another way that America provides settlement support is at the UN, although America's recent veto of a resolution criticizing settlements forced them to break cover, which they did not like. The American government often makes official statements, such as this one, that are critical of settlements. They are meaningless jibber jabber and are meant to be ignored by Israel but taken seriously by everybody else. People are not as stupid as American and Israeli politicians think they are. They know what's going on. They are just not motivated to do anything about it at the moment.
