The Defence plan,Many many many left attack it.
TMD(Theater Missile Defence)
They insist that

That's perfect money waste.
If US and Japan develop that, China and Russia would develop better ballistic missile.
China would advance opening economy and democratized soon.
NKkorea has no food,no oil, and can,t attack south

Certainly, their insistence may be reasonable.
But,I think Stopping TMD may 2nd Acheson statement

HONOLULU — A U.S. Navy ship at sea successfully shot down a target test missile in its last few seconds of flight, the military said on Wednesday.
Until the test off Hawaii, only ground-based interceptors have shot down targets in their final stage. Ships had only intercepted target missiles in the early or middle stages of flight.
The interceptor is part of the Missile Defense Agency's multibillion-dollar program to protect the United States and its allies from an enemy missile attack.
Rear Adm. Barry McCullough, director of surface warfare on the staff of the chief of naval operations, said in a statement that the test was an important step toward enabling ships to shoot down ballistic missiles as they are about to hit their targets.
He said Patriot Advanced Capability 3, or PAC-3, missiles are currently the only interceptors the military has that are able to shoot down terminal phase target missiles.
For Wednesday's test, the Pearl Harbor-based USS Lake Erie launched a Standard Missile 2 to shoot down a missile fired from the Pacific Missile Range Facility on Kauai.
