Yesterday's failed coup attempt in Venezuela significantly hurt the Trump administration's international standing. It delegitimized its Venezuelan clients Juan Guaidó and Leopoldo López. After recognizing that their original 'regime change' plan failed (again) the White House starts to beat the war drums.

That wasn't the plan:

The Trump administration, which has backed Mr. Guaidó since he first challenged Mr. Maduro’s authority more than three months ago, clearly thought the day would unfold differently.
There is no official explanation why the Trump administration believed that the comical coup attempt by Juan Guaidó and his master Leopolo López would work.

There are signs though that the government of President Nicolas Maduro set a trap. Several people in the top echelon of the Venezuelan government gave false promises that they would join the U.S. proxy side. They snookered Guaidó into launching his coup to let him fail.

A Washington Post wrap-up says that everyone expected important people to change sides:

The chaos in Caracas indicated that, while a plan had been in motion, it may not have unfolded as anticipated.
...
Announcements by senior Maduro officials that they were changing sides did not materialize, and the administration appeared increasingly concerned as it debated next steps.
...
Earlier Tuesday, Bolton had told reporters that Trump is watching political developments in Venezuela “minute by minute.” Bolton also put unusual public pressure on individual Venezuela government officials to renounce Maduro and embrace the political opposition.
...
“It’s a very delicate moment,” Bolton said. “The president wants to see a peaceful transfer of power,” which he added would be possible if enough military and government figures switch allegiances.
...
In an apparent attempt to divide Maduro’s government, Bolton said senior officials, including Defense Minister Vladimir Padrino López, had been in secret talks with Guaidó, and he called on them to “make good on their commitments” to help oust Maduro.
...
Bolton called by name for three officials in Venezuela — the defense minister, the chief judge of the Supreme Court, and the commander of the presidential guard — to support Guaidó taking power.
...
A senior Latin American official said opposition talks had been going on with Padrino and the other two for “the last several weeks,” and that the three had been promised retention in their current positions if they came out publicly in support of “constitutional order” that would allow Guaidó to take power. The official, who spoke on the condition of anonymity about the fast-moving and confusing situation, said those involved in the negotiations had no initial explanation for what went wrong, ...
...
Elliott Abrams, the administration’s special envoy for Venezuela, told reporters Tuesday that the United States had expected Padrino, along with the head of the Maduro-appointed Supreme Court and the head of the national guard, to declare their support for the Venezuelan constitution, if not necessarily for Guaidó himself.
...
He said that opposition figures had held discussions with the three influential officials in Maduro’s government ahead of those planned demonstrations.
...
Carlos Vecchio, Guaidó’s ambassador to the United States, also said Monday that the opposition leadership had had “conversations with part of the inner circle of Maduro” and that “they know that Maduro is not going anywhere. That Maduro is the past . . . and that’s why they want to look for a different future for Venezuela.”

Everyone in Washington believed that significant figures in the Venezuelan government would change sides. They did not do so. Vladimir Padrino rejected the coup within an hour after Guaidó announced it. It seems that the Guaidó side got played by the Venezuelan Defense Minister and several other officials and officers. They seem to have promised to support Guaidó only to bait him into taking steps that would embarrass him.
