You don't, (Western) Europe is just a rentier-place at this point, living on other people's backs. For example look at Maersk, from the much-beloved and relaxed Denmark, their business would crumble over night if it weren't for the Americans keeping the seas open for them.
Bad timing with that example - currently the US is the reason for an important part of the seas being closed :)
Americans seems to be intent to cause as much damage to everyone including themselves.
USA is the only country that ever triggered article 5 of NATO and got military help out of it. And now acts like victims when others don't rush to help them with absurd badly planned war where they are clear aggressors.
The second real use of NATO was to send armies to greenland to discourage USA to attack it just 2 months ago. So, now is really not the time for America to pretend ever do something that is not primary for itself.
The Americans are keeping the seas open for their own self-interest, and this is great. Other countries in the broader West do also chip in with their own military assets. Why should Maersk have a problem with this?
