Trump has drawn three red lines. They’re all likely to be crossed.

The Trump administration has in fact, either accidentally or by design, laid out aggressive markers in three parts of the world — three red lines — without any serious strategy as to what happens when they are crossed.

.. The president has specifically promised that North Korea would never be able to develop a nuclear weapon that could reach the United States. Meanwhile, CIA Director Mike Pompeo says Pyongyang is “a handful of months” away from having this capability.

.. So what happens when that red line is crossed? What would be the American response? Victor Cha, a seasoned expert who was expected to be the nominee for ambassador to South Korea, told the administration that there really is no limited military option, not even a small strike that would “bloody” the nose of the North Korean regime. For this frank analysis, he was promptly droppedfrom consideration for the ambassadorship.

.. But being right is not the same as being smart. Most experts predicted that Pakistan would respond to the U.S. action in two ways: First, by pursuing closer relations with China, which can easily replace the aid. Second, the Pakistani military would ratchet up the violence in Afghanistan, demonstrating that it has the capacity to destabilize the pro-American government in Kabul, throw the country into chaos and tie down the U.S. forces that are now in their 17th year of war.
.. Thomas Schelling, the Nobel Prize-winning scholar of strategy, once remarked that two things are very expensive in international affairs: threats when they fail, and promises when they succeed. So, he implied, be very careful about making either one.
.. Trump seemed to understand this when his predecessor made a threat toward Syria in 2013, and Trump tweeted: “Red line statement was a disaster for President Obama.” Well, he has just drawn three red lines of his own, and each of them is likely to be crossed.
