Here is the tactic that Zelinsky is playing, and try not to underestimate him. He is looking at this in dollars and cents. If he let's the US mine rare earth minerals, that is a deficit to his countries future natural resources and wealth, let's say equal to the value that he has been given by the US $350 billion. He owes us $350 billion, so by disrespecting Trump and the administration, he is up $350 for resources and $350 in US aid which equals $700 billion because he gets to keep the rare earth minerals. If he let us in, he is just paying back the $350 billion and breaking even at best. What he doesn't realize, is that after he loses and is dead, the US and Russia will agree on the recap. We will break even, and have peace, and he will be gone and probably most of his country will be taken by Russia is not entirely. So he would rather at this point, take more loans from EU, and hopefully get some weaponry, but that will eventually run out as soon as Russia cuts off the oil. Not too bright.
