OK, so an invasion, or Venezuelan action would not be overlooked. Wonder why they did not bring up the Rio Treaty and why the OAS is so silent on this matter.

Here is the Treaty.
Office of the Spokesperson
Secretary of State Antony J. Blinken spoke with Guyanese President Dr. Mohamed Irfaan Ali to reaffirm the United States’ unwavering support for Guyana’s sovereignty. The Secretary reiterated the United States’ call for a peaceful resolution to the dispute and for all parties to respect the 1899 arbitral award determining the land boundary between Venezuela and Guyana, unless, or until, the parties reach a new agreement, or a competent legal body decides otherwise. Secretary Blinken and President Ali noted the International Court of Justice order issued on December 1, which called for parties to refrain from any action that might aggravate or extend the dispute. The Secretary reiterated that the United States looks forward to working closely with Guyana once it assumes its non-permanent seat on the United Nations Security Council in January 2024. The two leaders concluded the call by agreeing upon the importance of maintaining a peaceful and democratic Western Hemisphere.
