So wrote Lord Byron of Greece's war of independence against the Turks, though the famed British poet would ignore his own counsel and die just days after arriving in Greece to join the struggle.

Yet Byron's advice is the wise course for the United States, and for the people of Venezuela who seek to free their country of the grip of the incompetent and dictatorial regime of Nicolas Maduro.

Let the Venezuelans decide their own destiny, as did we.

As of today, Caracas seems to be in something of a standoff.

Opposition leader Juan Guaido, recognized by the U.S. and 50 other nations as president, has failed to persuade the army to abandon Maduro.

Yet he can still muster larger crowds in the streets of Caracas to demand the ouster of Maduro than Maduro can call out to stand by his regime.

Tuesday and Wednesday, Guaido announced that the regime's final hour was at hand. But by midweek, the army's leaders, including the minister of defense, still stood with Maduro.

Guaido's opportunity seems to have passed by, at least for the moment. Maduro remains in power, though his generals, weighing the odds, have apparently been negotiating in secret with Guaido.

The Trump administration has backed Guaido, only to see him fail twice now at taking power.

The White House backed the plan in February to breach Venezuela's borders with truckloads of food and medicine, counting on the army not to use force to block the trucks.

Vice President Mike Pence traveled to the border.

But Guaido and the Americans miscalculated. The army stood by Maduro. The trucks were kept out.

This week, when Guaido called out the crowds again to bring the strongman down, the White House went all in. President Donald Trump, Pence, Secretary of State Mike Pompeo and John Bolton all tweeted support for the uprising.

But by Thursday, it was again clear that no matter what Washington had been told and anticipated, the army remained loyal to Maduro.

Frustrated, exasperated, appearing at once bellicose and impotent, Washington has now begun to bluster about military intervention.

"All options are on the table," says Joint Chiefs of Staff Chairman Gen. Joseph Dunford. Presumably that includes the 82nd Airborne.

"While a peaceful solution is desirable, military action is possible," said Pompeo. "If that's what required, that's what the United States will do."

"All options are open," says Bolton. "We want a peaceful transfer of power. But we are not going to see Guaido mistreated by this regime."
