The RMS Lusitania was a ship that sailed from New York and had American civilians in - at that point the US was neutral in the WWI -, when the ship came to the sight of the Irish Coast the German U-boat attacked it.
Despite the fact that Americans were horrified at the Lusitania attack, many Americans did not like the idea to enter the war, Irish Americans did not enjoy the idea of helping Britain because the country denied Ireland its independence, German Americans were sympathetic towards their ancestral homeland and Americans saw no reason to enter into a war between European powers. The US only entered war two and a half years after it started.
If you're referring to new non-European states that have risen since the Cold War Ended, then the effect has perhaps been minimal in terms of their daily lives, but if they have close relations with the US it would mean a stronger connection.

These rights are freedom of religion; freedom of speech, press, petition and assembly; privacy; due process of law; and equality before the law.
