I will go straight to point 4. France, Spain and Portugal are all free countries and yet they don't get involved in playing 'big boy'. None of them had any real involvement in Iraq, Kuwait, Syria and every other conflict we have managed to pretend we are doing some good whilst beating our chests like Tarzan. If Iran does go on to be fully nuclear who are they going to threaten ? none of the 3 I have just mentioned but I bet we are first on the list as we are seen as the aggressors and Trumps puppets.. If they threaten Israel who is going to leap up and defend them, again not the three I have mentioned.
My point is, we seized the tanker as it was breaking EU sanctions, where were the other countries when this was going on ? where was the vocal support after ? The Spanish government sat there moaning about Gibraltar being theirs, so much for unity.
