We still have a struggling army. If we were to send troops to Russia/Ukraine, we would be at a stretch to provide 2 brigades, about 8000 men. I doub t the 'coalition of the willing' could provide more than 40,000 troops. How many troops does Putin have on the ground? 1,000,000?
US has 18 ships inc 2 aircraft carriers in the middle east and up to 40,000 men, to keep the Suez Canal open for mainly European trade and to keep the Houthis at bay, we have 2 warships, the Italians have a frigate, the French might have a couple of ships.
