Showing Protect and Defend by Vince Flynn

With Iran on the brink of developing a nuclear weapon, Israel is forced to react. But by destroying Iran's main nuclear facility, creating a radioactive tomb and an environmental disaster, Israel has triggered an international crisis. An outraged United Nations condemns the attacks, while Iran swears vengeance against Israel and her chief backer: the USA.
Enter Lebanese master terrorist Imad Mukhtar, who's spent the past decade picking his targets and preparing his cells for this exact moment. All he needs is approval from Iran's Supreme Council, and he will strike at America's soft underbelly and make her bleed like never before.
With the US on high alert, the President calls on the one man ruthless enough to counter the fanatical terrorist. Meeting violence with violence, CIA operative Mitch Rapp tracks his mark across Europe to America where they are finally pitted against each other in a hunt only one of them can survive.
