The important part is the line that says "no non NATO countries may have bases there."


 No it doesn't.  It says "no state that is not a member of NATO shall be allowed to establish its own manned or unmanned military installations in Greenland nor shall they be allowed a persistent presence of military forces in Greenland"

 This agreement does not "lock" the US into NATO membership, but it does "lock" Greenland into NATO membership if Greenland becomes it's own country:

In case Greenland exercises its right to self-determination to become independent, the Government of the Kingdom of Denmark and the Government of Greenland shall together ensure that the independent Greenlandic state will (i) agree to remain in NATO, including by applying to become a member if necessary, and (ii) affirmatively assume, as from the date of independence, all of the rights and obligations of the Kingdom of Denmark specified in this Agreement, including any implementation agreements or arrangements between the Parties, as well as the Defense Arrangements.


 Nothing in the document states the US must remain in NATO.  

 A reference that will not be acknowledged so people can say I "never" provide references for "anything" I say:

 Sure but then we will just go invade Greenland.  It is my opinion trump will just go back to his invade Greenland strategy.  And, in my opinion, it will be easier because we already have bases there!  This is an opinion.
