Columbia is has enough problems of its own without picking a fight with the US, they have a major war with drug gangs. I don’t think it’s unreasonable for the US to want control of its borders.
The US needs migrants, just like us it wants to control who is allowed in, Biden had a virtual open border, picking up those that crossed and shipping them to cities across the country. There isnt going to be a big falling out with Mexico, or Canada as with Columbia a deal will be done in the interest of both.
Greenland is different, the US would be really stupid to allow China or Russia to establish influence there, certainly not military bases. They could walk in tomorrow, my guess is they won’t but it will be a continuing issue whoever is governing the US.
