The lecturing and scolding from over there as if Trump were rational and even-tempered is wrong wrong wrong. You think Trump is "being tough" when Trump is being the moron idiot ignoramus dope those around him have stated he is. Moreover, if Trump is employing a "bluffing strategy" as you claim he is then if you know about it then Kim knows about it too eh. So you're welcome to play Russian Roulette and I'll be pleased to enable and assist you to the maximum extent possible.
You refer to Reagan and repeatedly, as if Reagan himself were not the end of dayze guy that Reagan wuz....
In May 1982, the New York Times revealed that President Reagan had committed the United States to fighting a protracted nuclear war -- lasting up to six months. "A war in which the U.S. could prevail and force the Soviet Union to seek earliest termination of hostilities on terms favorable to the United States."
_New York Times, May 1982
In 1982 President Reagan called the Soviet Union an "Evil Empire" and described his "plan and hope for the march of freedom and democracy which will leave Marxism-Leninism on the ash-heap of history."
__President Reagan, June 1981
"We could wage and win a Cuban missile crisis today."
__Arms Control Agency head, Walter Rostow, 1983
During his 1980s Presidential campaign, Reagan told Fundamentalist Christian groups that he believed in the Biblical prophecy of Armageddon and that this could be the generation that sees Armageddon.
_President Reagan, Oct. 1984
Responding to President Reagan's belief in Armageddon, 100 American religious leaders signed a statement saying that they "find President Reagan's belief in the imminence of Armageddon profoundly disturbing."
_100 Christian Ministers, Oct. 1984
In May 1981, in response to President Reagan's aggressive talk about nuclear war, the Soviet Union instituted the RYAN (Nuclear-Rocket Attack) program, which created a "heightened state of intelligence alert."
In 1983 the RYAN program and Soviet paranoia over an American nuclear attack reached a new peak with the Soviet shooting-down of a Korean airliner that strayed into Soviet airspace over a top-secret missile warning installation in early September 1983. The shooting down of this commercial airliner was in part caused by increasing Soviet anxiety over what they considered an "imminent American nuclear attack." The Soviets believed that the November 1983 NATO exercise, Able Archer 83, designed to practice "command coordination" for a NATO nuclear attack, was in fact not an exercise at all but an actual Western nuclear strike against the Soviet Union. During this NATO exercise in November, the Soviets put their military forces on alert and prepared for a Western attack. See Martin Walker, The Cold War (pp. 274-75)
Rejecting MAD, Reagan brought out the NUTS strategy -- Nuclear Utilization Target Selection -- which called for the United States to have so many nuclear weapons that it could not only destroy the Soviet Union but it could destroy enough of the Soviets nuclear weapons so that the United States could fight and win a full-scale nuclear war. This NUTS strategy was based on what Secretary of Defense Casper Weinberger called an "American First Strike" capability, that is, we would have enough nuclear weapons to destroy the Soviet Union and destroy its nuclear arsenal with a nuclear first strike.

Reagan set in sequence a $3 Trillion increased defense expenditure during the 1980s. Reagan's arms programs and committed contracts through 1997 increased the national debt from $970 billion in 1980 to $5.4 Trillion in 1997. Then came the post 9/11 wars in Iraq and Afghanistan.
President Kennedy never talked in these ways nor -- it is entirely a certainty -- did JFK ever think in these ways. The Russian Soviet Union is gone but now we have Trump-Putin-Trump-Kelly vs our faithful generals holding 'em off, the CCP Dictator-Tyrants in Beijing, Kim III, the Ayatollahs in Iran, al Qaeda, Taliban, ISIS, Stephen Bannon, Roy Moore and DP rightwingers extreme. It's what I'd call a full plate to say the least and lined with nuts.
