Countries urged to take nukes off alert

Ex- commander says step back could foil hackers

WASHINGTON — Taking U. S. and Russian missiles off high alert could keep a possible cyberattack from starting a nuclear war, a former commander of U. S. nuclear forces says, but neither country appears willing to increase the lead- time to prepare the weapons for launch.

Retired Gen. James Cartwright said in an interview that “de- alerting” nuclear arsenals could foil hackers by reducing the chance of firing a weapon in response to a false warning of attack.

Essentially adding a longer fuse can be done without eroding the weapons’ deterrent value, said Cartwright, who headed Strategic Command from 2004 to 2007 and was vice chairman of the Joint Chiefs of Staff before retiring in 2011.

The Obama administration has considered and rejected the idea before of taking nuclear missiles off high alert.

There appears to be little near- term chance that Moscow would agree to pursue this or any other kind of nuclear arms control measure, given the deteriorating U. S.- Russian relations after Russia’s intervention in eastern Ukraine.

The U. S. and Russia also are at odds over a U. S. accusation that Moscow is violating a treaty banning medium- range nuclear missiles.

Robert Scher, the Pentagon’s top nuclear policy official, told Congress this month that “it did not make any great sense to de- alert forces” because the administration believes the missiles “needed to be ready and effective and able to prosecute the mission at any point in time.”

An example of the high alert level of U. S. nuclear weapons is the land- based nuclear force.

These are the 450 Minuteman 3 missiles that are kept ready, 24/ 7, to launch from underground silos within minutes after receiving a presidential order.

A study led by Cartwright proposes to adjust the missile command and control system so that it would take 24 hours to 72 hours to get the missiles ready for launch.

Cartwright said cyberthreats to the systems that command and control U. S. nuclear weapons demand greater attention.

While the main worry once was a hacker acting alone, today it is a hostile nation- state, he said, that poses more of a threat even as the Pentagon has improved its cyberdefenses.

Defense officials are tight- lipped about countering this type of cyber threat.
