It’s been a few weeks since Christiane Amanpour took over “This Week” on ABC. At first it just seemed awkward, with foreign and world politics being shoehorned into a program known for domestic politics and a forum for talking heads to duke it out with each other. But since then I’ve quite warmed to it. With the world becoming smaller and tighter knit, it gives good prospective to the decisions that are being made in Washington and the debates that surround them. Watching “Meet the Press” afterwards just seems trite and petty.
