This is not different from slapping sanction on some companies which sold critical military technology to an enemy state.

Trump tries to win a war without firing a shot. We are way past the stage where we can quibble and haggle about details to make sure we have perfect solution which cause damage to nobody except the intended target. We are left with blunt instruments to get the job done. If this is not allowed, then there will be real fireworks.
