The United States acknowledged that it had held talks with senior Venezuelan representatives. Why did Guaido become an abandoned child of the United States so soon?

I think it must be that the United States thought it was profitable to support Guaido at first, but later found that the intervention and interference of various countries led to a loss-making transaction and gave up in order to stop the loss.

When the Venezuelan regime crisis broke out, the United States vowed to overthrow the Maduro regime. However, after Russian military forces entered Venezuela to support Maduro's regime, the United States no longer insisted on overthrowing Maduro's regime, and its position on Venezuela began to change. The entry of Russian military forces into Venezuela has completely stabilized the Maduro regime, and the United States has been unable to effectively interfere in Venezuela's internal affairs. With Russian military strength, the United States dare not overthrow the Maduro regime by force. A military conflict with Russia at the doorstep of the United States is the last thing the United States wants to see. The Venezuelan war will plunge the United States into panic and turmoil.

Guaido has long been an abandoned child of the United States. If the United States negotiates with the Maduro regime, the United States must give up Guaido. There is a lot of room for negotiation between the United States and Maduro. As long as the Maduro regime can accept the US oil interests in Venezuela and recognize the monopoly position of Venezuela's petrodollar hegemony, the United States will not insist that Maduro step down.

The United States should not only safeguard its own oil interests in Venezuela, but also monopolize Venezuela's oil interests. The United States must support pro-American forces to come to power. Venezuela can better safeguard the interests of the United States only if the pro-American forces are in power, but it cannot have both. If the Maduro regime cannot be overthrown, the minimum requirement of the United States is that the cake of American oil interests in Venezuela cannot be reduced. Profitable people will come, and unprofitable people will naturally be abandoned by some "unscrupulous people." This is an indisputable fact in the present society.
