Threatswatch reports that:

While Iraqi Prime Minister Nuri al-Maliki met first with Prime Minister Tony Blair in Britain on Monday and then with President Bush in Washington D.C. on Tuesday to much fanfare, a less heralded but possibly more significant showing was made in Baghdad as followers of the radical Shia cleric Muqtada al-Sadr made their gravest threats yet against the Iraqi government. Occupying the grounds around the prime minister’s office with a sit-in, Sadr’s followers demanded that Maliki cancel his trip to Washington in protest against attacks on Sadr’s Mahdi Army, which has been blamed for the most gruesome attacks on Sunni civilians. U.S. and Iraqi troops have increased operations against members of the Mahdi Army and the Sadrists are responding by threatening to wage war on U.S. troops and, apparently for the first time, against the Iraqi government itself.

Al-Sadr’s threats and his militia’s actions are akin to the activities of their Hezbollah brethren. They have gone too far and the axe is about to fall.
