According to its name, the alliance's goal is to fight drugs by all means, first in the Americas region, but not limited to this region.
In essence, the establishment of the alliance is a specific step in Mr. Trump's new national security strategy, with the central goal of restoring Central and South America to its "backyard" and its own sphere of influence.
In addition to the goal of shielding the Americas from all activities related to drug trafficking and transportation, Mr. Trump also wants to prevent illegal entry into the US and push back the influence of external partners out of the area that the US considers its backyard.
The birth of this alliance is a new step in the US's rearrangement of its "backyard". Therefore, it can be seen that Mr. Trump uses the "Defense for America" first and foremost as a tool to protect and promote US interests in the region.
Gathering countries in the region into an alliance helps the US easily lead and shape the situation. This alliance also creates conditions for the US to push back the influence of external partners, while opening up a legal basis for the use of military measures or political intervention under the guise of drug control and preventing illegal immigration.
In addition, the alliance also reflects the ideological gathering of countries in the region who have views close to Mr. Trump.
Although the coalition only has a few countries in the region participating, this is still a useful foreign policy achievement for Mr. Trump's domestic goals. He can exploit the topic of anti-drugs and preventing illegal immigration to strengthen support for the Republican Party in the upcoming midterm congressional elections in the US.
