US President George W Bush warned the Iraqi government Saturday that it must get tougher on the insurgency or face the consequences, according to Deutsche Presse Agentur dpa. Addressing opposition Democrats in Williamsburg, Virginia, Bush said the US military commitment to Iraq was not limitless. Prime Minister Nuri al-Maliki's government must play a leading role in combatting the terrorism of the insurgency and go ahead with the political reforms needed to give Iraqis the feeling that the government was there for them. "There's got to be success not only on the military front - in other words, the Iraqis have got to be taking the lead in Baghdad to secure its capital, but there's also got to be success on the political front," Bush said. "They've got to pass an oil law. They've got to amend their constitution so that all segments of that society feel that the government is for them. "We've got to spend our money on reconstruction projects that help unite the country. They've got to have local elections so people feel involved in the provincial governments. "In other words, there's benchmarks that they have got to achieve. And I have made it clear to the Iraqi government, just like I made it clear to the American people, our commitment is not open-ended."
