Guess who fears missile defense

 Time:

President Donald Trump has promised a “Golden Dome” that will protect the United States. But America’s rivals see the announcement last week of the plans for a new space-based missile defense system as provocation.

Trump’s proposal, which as proposed remains years away from being operational, has many uncertainties, not least cost. The “Golden Dome,” modeled after Israel’s “Iron Dome,” would consist of a constellation of interceptors, satellites, and sensors “capable of intercepting missiles even if they are launched from other sides of the world,” according to the President.

But the biggest question is whether it would even make the U.S. and world safer. Critics have raised concerns that the effort to create such a shield would raise suspicions and exacerbate a global arms race as well as accelerate the weaponization of space.

North Korean state media on May 27 reported that the foreign ministry condemned Trump’s proposed “Golden Dome,” saying it was an “outer space nuclear war scenario supporting the U.S. strategy for uni-polar domination,” and added that it was a “typical product of ‘America first’, the height of self-righteousness, arrogance, high-handed and arbitrary practice.”

Earlier this month, before Trump announced the Golden Dome project from the Oval Office but after having discussed the idea for many months, Russia issued a joint statement with China in which they called the planned program “deeply destabilizing in nature.” In the statement, the two countries said the Golden Dome was “a complete and ultimate rejection to recognize the existence of the inseparable interrelationship between strategic offensive arms and strategic defensive arms.” It also opposed how countries are using space for armed conflict, saying that it will jointly counter security policies and activities aimed at using outer space as a ”warfighting domain.”

After issuing the joint statement with Russia, China continued to criticize the U.S. over its Golden Dome plan, urging Trump to trash it.

“The project will heighten the risk of turning the space into a war zone and creating a space arms race, and shake the international security and arms control system,” Foreign Ministry Spokesperson Mao Ning said in a regular press briefing on May 21.

The real concern for adversaries of the US is that they can no longer threaten US security.  The defensive weapon systems are about saving American lives.  China, North Korea, and Russia fear that they can no longer threaten the US.
