This is the right thing to do.
Why?
Never mind the Gulf of Tonkin stench around this provocation, ask yourself why on earth is a Ukrainian tug going under a Russian bridge with a gunboat escort?
How would you expect our coast guard to react if a Cuban tug with two gunboats decided to sail under the Brooklyn Bridge and didn't heed instructions?
This smells like a setup to derail presidential talks, as well as provide an unpopular puppet in Ukraine with martial law leading up to the next election.
The Russian bridge is on illegally occupied Ukrainian territory and it crosses a formally recognized international waterway. The Ukrainians have a right to pass that strait and so does anyone else who wants to pass there. The Russian bridge did not change that status as an international waterway...just the same as China’s artificial islands do not change the facts of the South China Sea.
Big difference from how you frame this issue.
Our coast guard wouldn’t be using a bridge deliberately built to prevent another nation from using sealanes to engage in free commerce.
