United States President Donald Trump wishes to carry out a shoot-to-kill policy on the US/Mexico border if any of the migrants throw stones at US troops.

And this guy, President Donald Trump, has the nuclear football?

We know all about shoot-to-kill in Ireland. Fourteen unarmed protestors were killed by the British Army on Bloody Sunday, in 1972. The British never recovered their international reputation and ended up losing a case at the European Court of Human Rights - a forever stain on their army.

Imagine what killing unarmed Campesinos, men, women, and children will do for the American image already in tatters worldwide?

More worrying is what would Trump do if there was a real war? If he is prepared to kill unarmed refugees what measures would he use on a real battlefield? Nuclear weapons anyone?

He clearly likes to play soldiers like many draft dodger presidents. This has always been a massive weakness when macho swagger replaces quiet diplomacy - see George Bush and the Iraq invasion.

If Trump considers the rag, tag, and bobtail column currently wending across Mexico seeking sanctuary as an invading force what would he do if North Korea made a fool of him as they appear to be doing?

How long before the nuclear football is kicked into action? Maybe a dry run on the women and children in the caravan? He could never stop winning. A nice big fat nuclear cloud over Tijuana could be described by one of his favorite words - “beautiful”.

There is no armor against incompetence allied with arrogance.

The use of the Roosevelt Room in the White House to attack the immigrant convoy for political gain was the worst abuse of American presidential power since Ronald Reagan decided to attack Grenada which has a population half the size of Yonkers, New York.

Trump has the definition of deviant leadership down.

He is a tin-pot general wasting the reputation, training time, and expertise of the greatest army on earth on a yet-to-arrive desperate band of refugees which will likely measure in the low hundreds by the time it reaches the border.

If you want to talk invasion Mr. President, consider the Russian infiltration of our sacred electoral system. An international crime that your National Security advisor laughed off during a meeting with Russian President Vladimir Putin.

And if you want to talk American power consider what one diplomat, Senator George Mitchell did - not armed with guns but with the tools of international diplomacy. He and the US played a huge role in bringing peace to Ireland.

It was achieved using America’s soft power and international leadership, a concept no longer valid under your watch as you carouse with enemies and bash our allies. It feels like an enemy within, an Un-American American president as military expert Colonel Ralph Peters called him on CNN. It was an apt description.
