Sir: The figurative war of the nuclear buttons between the US and North Korea is a sad story. America seems to be doing all the right things in this regard whereas North Korea is always acting on impulse, not caring about anything. Sometime ago, the nuclear water leak at Fukushima nuclear plant in Japan had appeared in the newspapers and on TVs. In fact this kind of radioactive fluid will pose severe health hazards like radiation sickness.Unfortunately, the incidents of contaminated water leak from the Fukushima plant into the ocean had long been reported since the plant was hit by the earthquake and tsunami in 2011. The undue fears on the nuclear plants have already bothered the people across the world. At the same time, safety should be on high priority when it comes to embracing greater technologies like nuclear types. It is the responsibility of the International Atomic Energy Agency to keep tabs on the countries like North Korea in order to nip any major tragedy in the bud. Interestingly enough, there were talks between Iran and America in the direction of easing the tension arising out of the Iranian nuclear activities then. Iran is the OPEC’s second largest crude supplier after Saudi Arabia. Any military attack on Iranian nuclear facility will only lead to crude oil crisis at the global stage.One can imagine the global economic crisis if Iran — a major oil supplier — is turned into a battlefield. In this context, the diplomatic efforts of Washington to convince Tehran to abandon its uranium facility had played a major role then. So, the US should try its diplomatic effort towards North Korea until the nuclear conflict is solved amicably. Finally, the countries all over the world should concentrate on the bigger issues like farm crisis, unemployment and economic slump.P Senthil Saravana MumbaiPublished in Daily Times, January 8th 2018.
