America Stands with Israel Act - Expresses the sense of Congress that the United States: (1) supports Israel's right to defend itself; (2) supports Israel's naval blockade of Gaza; and (3) should oppose any investigation by the United Nations (U.N.) into the flotilla incident (involving the May 2010 Israeli interception of ships carrying supplies to Gaza).
Requires the Secretary of State to direct the U.S. Permanent Representative to the United Nations to cease U.S. participation in and membership on the United Nations Human Rights Council (UNHRC).
Prohibits the Secretary from contributing any funds to the United Nations for an investigation into the flotilla incident.
Directs the Secretary to ensure that no U.S. contributions to the United Nations are used for any such investigation, including by withholding from U.S. contributions to the regularly assessed biennial budget of the United Nations amounts equal to any amounts so expended.
