Washington ? President Bush’s homeland security strategy says the United States faces grave threats of terrorism and needs broad new powers to fight back from possible domestic use of military forces to presidential authority for transferring money without congressional approval.

The 90-page document released Tuesday describes a shadowy, omnipresent threat of terrorist attacks from al-Qaida and other extremist groups. America faces “a new wave of terrorism, potentially involving the world’s most destructive weapons. … It is a challenge as formidable as any ever faced by our nation,” it says.

The threat must be met with a coordinated new approach, including creation of the Homeland Security Department now being considered by Congress, beefed-up spending in key areas and even changes in state laws, the strategy says.

Some of the more fundamental changes would involve the military. Bush suggests that Congress perform a “thorough review” of the Reconstruction-era “posse comitatus” law that bars use of the military in civilian law enforcement.

The strategy also contemplates giving the federal government greater authority to deploy the National Guard, which is now under state control. This would be coordinated under the new U.S. Northern Command, which is to “update plans to provide military support” including maintaining order or loaning equipment in cases of terrorist attacks or natural emergencies.

The blueprint advocates changes in state laws, including tighter uniform rules for obtaining a driver’s license, updated quarantine plans in case of a bioterrorism attack and making terrorism insurance available for businesses.

Under a section titled “the costs of homeland security,” the strategy notes that Bush asked Congress for $29 billion this year and will ask for $38 billion next year for the new Homeland Security Department.

The strategy seeks authority for the president to shift money within departments to meet evolving threats. In the case of the Homeland Security Department, Bush has asked for the ability to move up to 5 percent between programs without congressional approval.

Bush is unlikely to get all the new powers or spending he wants. For example, the House Appropriations Committee flatly rejected his request for budget transfer authority within the new Homeland Security agency without a green light from Congress.
