WASHINGTON
— Three years ago, President Barack Obama ordered Pentagon officials to
step up their cyber and electronic strikes against North Korea’s
missile program in hopes of sabotaging test launches in their opening
seconds.
[…]
The decision to intensify the cyber and electronic strikes, in early 2014, came after Mr. Obama concluded that the $300 billion spent
since the Eisenhower era on traditional antimissile systems, often
compared to hitting “a bullet with a bullet,” had failed the core
purpose of protecting the continental United States. Flight tests of
interceptors based in Alaska and California had an overall failure rate of 56 percent, under near-perfect conditions. Privately, many experts warned the system would fare worse in real combat.
So
the Obama administration searched for a better way to destroy missiles.
It reached for techniques the Pentagon had long been experimenting with
under the rubric of “left of launch,”
because the attacks begin before the missiles ever reach the launchpad,
or just as they lift off. For years, the Pentagon’s most senior
officers and officials have publicly advocated these kinds of
sophisticated attacks in little-noticed testimony to Congress and at
defense conferences.
