Republican party leaders may have worried that Donald Trump would not only lose the general election for the presidency, but would so poison the image of the party as to cause Republican candidates for Congress and for state and local offices to also lose. Now they seem to be trying to patch things up, in order to present an image of unity before the general elections this fall.

For decades after Republican President Herbert Hoover was demonized because the Great Depression of the 1930s began on his watch, Democrats warned repeatedly, in a series of later presidential elections, that a vote for the Republican candidate was a vote to return to the days of Herbert Hoover.

It was 20 years before another Republican was elected president.

The point is that Hoover was still being used as a bogeyman, more than 40 years after he left office. Trump’s image could easily play a very similar role.

The political damage of Donald Trump to the Republican party is completely overshadowed by the damage he can do to the country and to the world, with his unending reckless and irresponsible statements. Just this week, Trump blithely remarked that South Korea should be left to its own defenses.

Whatever the merits or demerits of that as a policy, announcing it to the whole world in advance risks encouraging North Korea to invade South Korea — as it did back in 1950, after careless words by a high American official left the impression that South Korea was not included in the American defense perimeter.

The old World War II phrase — “loose lips sink ships” — applies on land and water. And no one has looser lips than Donald Trump, who repeatedly spouts whatever half-baked idea pops into his head.

Nations risk their own survival when they ally themselves with the United States in the fight against international terrorists — and we need their cooperation in that fight.

If nations cannot have confidence in American commitments and leadership, we are not likely to get their cooperation. And the stakes are life and death.

What the Republican establishment once feared most — that Trump would lose the nomination and run on a third party — now seems to be a danger that has passed. But a far larger danger to something far more important, American society, is that Trump could be elected President of the United States.

Those who talk about “the will of the people” need to know that neither Donald Trump nor Hillary Clinton represents the will of the people. Polls repeatedly show these two with the highest negative reactions of any of the candidates in either party. A majority of the people polled have negative reactions to each.

What was once feared most by the Republican establishment — a third party candidate for President — may represent the only slim chance for saving this country from a catastrophic administration in an age of proliferating nuclear weapons.

If a third party candidate could divide the vote enough to prevent anyone from getting an electoral college majority, that would throw the election into the House of Representatives, where any semblance of sanity could produce a better president than these two.
