Islamic State¡¯s beheading of a U.S. journalist and its threat to ¡°destroy the American cross¡± suggests it has gained enough confidence seizing large areas of Iraq and Syria to take aim at American targets despite the risks.

On Tuesday night, Islamic State released a video of its fighters beheading James Foley, who was kidnapped in Syria nearly two years ago.

The black-clad executioner, who spoke English with a British accent, also produced another American journalist and said his fate depends on U.S. President Barack Obama¡¯s next move.
