It's a show of power that, for the US, is lessening that power.

Most of the US's power is from being a land of opportunity and of high ideals, with military power being secondary backup. As the US lessens opportunity and openly betrays its ideals, that power disappears. The Greenland and Canada threats alone probably require $500B-$1T/year in additional military spending to try to gain through force wha was previously given freely to the US. Add in the huge cost to the US from the tariff idiocy and cutting things like USAID and we could never spend enough militarily to make up for it.

Look at Putin's weakness in Ukraine. He tried to take by force what was not his, and ended up costing himself far more in lost trust than he could ever have gained with the war, and he has gained so little in the war. Putin had a better chance by continuing to try to divide Ukrainian society internally and have the majority of society side with Russia. Much like what is happening in the US right now.... but attack with bombs and the charade disappears. The US is going to discover the same loss of power through its attempts and threat of force.
