...still being fought in Mosul and Diyala province against al-Qaeda in Iraq. Iran continues to wage a hot and cold war for influence over the future of Iraq. Militant groups are trying to regain footholds around Baghdad. And Odierno's political skills have been put to the test in negotiations over a status-of-forces agreement with the Iraqi government, which the Iraqi Cabinet endorsed on Nov. 16. Under the terms of the agreement, all U.S. forces will leave Iraq by the end of 2011. (During the presidential campaign, Barack Obama called for pulling out all combat brigades...

Abolishing tenure doesn't address problems of underfunding, overcrowding or improving students' home environments. And despite more than a century of social progress, the need to protect teachers from the whims (or the tyranny) of the community remains as important as ever - especially in science classrooms where the battle over evolutionary biology and creationism rages...
