President Trump engaging in negotiations with Kim Jong-un is likely going to be a failure, believes Steve Chapman of The Chicago Tribune. Nuclear weapons are far too essential to the regime for them to be given up. They guarantee that North Korea won’t be attacked. Kim trusting any promises that Trump makes as reason enough to disarm is improbable. In the past, his country has gone back on multiple promises made during negotiations. The US president’s criticism of the Iran Deal indicates that America’s interests change with each administration. To really forgo highly valuable nuclear weapons would require almost unthinkable concessions from Trump.
