America cannot stop North Korea from building long-range missiles

But maybe it can deter Pyongyang’s despot from using them

The definition of an intercontinental ballistic missile (ICBM) is one that can fly at least 5,500km (3,420 miles). The weapon that North Korea tested, with characteristic belligerence, on the Fourth of July, had a range of perhaps 6,700km (see article). So its claim to have built an ICBM is technically correct.....That is not quite as alarming as it sounds....
