The National Guard can be called to federal service to be stationed domestically (or is that homelandedly?) or overseas. However, the valid reasons are (10 USC §12406):

• the United States, or any of the Territories, Commonwealths, or possessions, is invaded or is in danger of invasion by a foreign nation;
• there is a rebellion or danger of a rebellion against the authority of the Government of the United States; or
• the President is unable with the regular forces to execute the laws of the United States

None of those currently seem to apply, do they?
