America and Israel face numerous shared challenges, including terrorism, weapons and nuclear proliferation, cyber warfare, and the spread of radical Islamist ideology. America can consistently depend on the beacon of stability represented by democratic Israel in the turbulent Middle East, where the two countries share the same national and homeland security concerns: the megalomaniacal vision of Iran’s ayatollahs, the threat of Sunni and Shiite Islamic terrorism, and the critical security requirements of vulnerable pro-US Arab regimes. Israel also invests heavily in the American economy and is one of the top 20 suppliers of direct investment in the US.
