U.S. President Donald Trump claimed on the 18th (local time) that the United States is increasing its troop deployment to Greenland, a strategic stronghold in the Arctic region, and has secured permanent U.S. control over Greenland's security.

Writing on social media platform Truth Social that day, President Trump stated, "I am pleased to announce that the United States has reached an agreement with the Kingdom of Denmark and Greenland."

Greenland is an autonomous territory of Denmark.

President Trump claimed that this agreement "fully resolves our numerous concerns by granting the United States permanent control over Greenland's security and all other necessary matters," adding, "There will be no cost to the United States."

He emphasized, "To ensure and safeguard the security of Greenland and the United States, the United States will forever have the full capability to carry out necessary operations in Greenland."

He continued, "From now on, no hostile forces of the United States will be able to establish bases, station troops, or make sensitive investments in Greenland without our explicit written approval."

President Trump stated, "We will immediately begin the process of establishing a large-scale military presence in appropriate areas of Greenland," adding, "We will thoroughly protect this place."

He added, "This is a wonderful solution for the United States, Denmark, Greenland, and all of our allies," and "We look forward to cooperating with the wonderful people of Denmark and Greenland toward a brilliant future for this massive and highly strategic land."

Danish Prime Minister Mette Frederiksen stated that the United States, Denmark, and Greenland will sign an agreement next week to strengthen security in the Arctic and North Atlantic regions, AFP reported.

In a statement, Prime Minister Frederiksen said, "I am pleased that a good agreement is in prospect for Greenland, the Kingdom of Denmark, and the United States," and noted that the agreement will be signed at a separate event organized on the sidelines of the UN General Assembly.

Since last year, President Trump has argued that Greenland should be annexed by the United States, citing reasons that if Russia or China were to take over Greenland, U.S. air and maritime security would be threatened and Denmark lacks the capability to defend against it.
