Londonderry 

Hi, Are you some one-issue POV-pushing nut?
Because WP is full of jerks like that.

It was Londonderry in news reports during the Troubles.
Londonderry, Londonderry, Londonderry. You used to hear it all the bloody time.
Ireland, Vietnam. Vietnam, Ireland. The 1960s, remember?
Then very occasionally in the 1970s, you would hear "Derry" and you would be left wondering, "Is this Derry place anywhere close to the famous Londonderry?"
In 1977, you don't just go on the web and look it up and discover these are synonyms.
Right?
And Balbo's visit to Londonderry did not occur in 1977, now did it?
Happy now?
Please don't put silly anachronisms into a serious article.
