AlHijjah 23, 1432, Nov 19, 2011, SPA -- A breakdown in high-stakes budget talks in the U.S. Congress could threaten plans for a missile defense shield in Europe, AP reported. Negotiators have shown little sign they will be able to meet next week's deadline for reducing the deficit by $1.2 trillion. If they fail to agree, a new law mandates cuts throughout the federal government, including a big slice of the defense budget. While it is not known what military spending would be cut, an expensive program aimed primarily at defending Europe is unlikely to be spared. The U.S. sees the missile defense system, aimed at countering threats, as part of its contribution to the NATO military alliance. With the United States often complaining that it makes a disproportionately large contribution to NATO, missile defense could be especially vulnerable to budget-cutters. "A missile defense system for NATO? It's going to be hard to keep people committed if they think the U.S. is picking up the tab for Europe," says Kurt Volker, who was ambassador to NATO at the end of former President George W. Bush's administration. Defense Secretary Leon Panetta has warned that the European missile defense program could be threatened if the special negotiating panel, known as the supercommittee, should fail to work out a deal. That suggestion, though, may have been intended mostly to nudge lawmakers to resolve their differences and avoid the automatic cuts to one of their favorite programs. It is still possible that supercommittee members could set aside intense partisan differences and reach a deal by Wednesday. And if they do not, Congress might find a way to cancel the cuts before they take effect in 2013.
