boycotting Ireland is too far of a stretch.
labeling the whole country of Ireland as a sidekick is too much.
Almost like the hammer being your only tool if you think all problems have to be fixed with nails. Boycotting American companies surely can extend to products made in Europe, i agree that's completely different than boycotting everything Ireland makes.
I think all English speaking countries in Europe are culturally closer to US because of the language which means they are more accessible for US companies as well. There are other countries that could have played the same game as Ireland did, but they would have had a much harder time because there would be a language barrier. Punishing Ireland for using their position doesn't seem fair either, it would be much better to not allow US companies to benefit from Ireland by not buying their products wherever they're made unless there is no suitable alternative.
I am not sure why you believe sinking ships is the only possible solution, but i'm not going to argue about it
