However, the sheer danger of having a group soldiers carrying a live atomic bomb in their backpacks wasnt realized by the pentagon. They were soldiers and not robots and there was no off-switch in case one of them went rogue. But, the military decided to take them and deployed them for decades even though they werent ever used. With the dismemberment of the Soviet Union and the successful common sense Strategic Arms Limitation Talks between the nuclear powers, the nuclear stockpiles were significantly reduced and other confidence-building measures were introduced and implemented by both parties. However, the countries relatively new to the nuclear era like North Korea, India, Pakistan and Israel have no intentions of giving away their weapons of mass destruction as they think of them as necessary deterrence. Almost all of them are actively pursuing tactical nukes and have probably developed them by now. US and Russia learned about it the hard way then the Cuban missile crisis almost led to a full-scale nuclear war. Afterward, they have been sensible about it. The emerging nuclear powers especially India and Pakistan need to think about it rationally and stop arms race in the region. Arms race leads to inequality of firepower and it leads to the smaller nations developing irresponsible weapons like these tactical nukes!
