Russia and Ukraine

[The Architect Of Fate]

The US already has access to the Black Sea and already has alliances with countries that border Russia and Russia already has military bases a stone's throw away from US territory so why would they need Mexico?

I am not educated in geopolitics. But its obvious that its all about the money/influence. Why else USA has military bases all over the world? To hoard money and influence. Just like in medievel times, only now people pretend to be noble.

EDIT:

Here are the quotes of an educated man in geopolitics.

“The reality is that the American people have no desire for an empire. This is not to say that they don't want the benefits, both economic and strategic. It simply means that they don't want to pay the price. Economically, Americans want the growth potential of open markets but not the pains. Politically, they want to have an enormous influence, but not the resentment of the world. Military, they want to be protected from dangers but not to bear the burdens of long-term strategy.”

― George Friedman, 

Another quote:

There are three global realities that must be faced in the coming decade. First, the United States has become an empire, shaping and reshaping the world through its actions. Second, it is an unintended empire, which means that it neither recognizes the reality of empire nor is prepared to exercise that power prudently. Finally, the greatest challenge to that empire does not come from outside, but from the profound tension between empire and republic.

Well there are truths to these quotes Ukraine is a bit unique because I have pointed out there is nothing on a broad geopolitical scale America gains from Ukraine they don't already have and  if the goal is merely to screw over Russia they already can do that from territories they already have influence over.
