When I was a lad, I went to a nation to learn things that I didn't know. Twas much fun I had, twas like a vacation, until it was my time to go. Now far, far away perhaps it's ironic ne'er did I depart that nation. Til my dying day, condition is chronic, not there, but no emigration.
This is actually a true story. Can you tell me the nation where I was that I never left, despite being thousands of miles away now?
UPDATE: There are several situations that could match my reality, so let me be more specific. The trip in question took place in 1991.
UPDATE: @mohirl has the correct answer below, so some details for anybody looking to kill a minute:
I went to Lake Bled in Yugoslavia to attend a math conference, knowing that the Slovenes planned to declare independence while I was there. It was a great time, until...independence was announced on June 25, 1991 (Croatia declared at the same time), but the morning of June 26 was when conflict started. Compared to what later happened in Croatia and Bosnia, it was nothing...just conscripts running around the train station with Uzis, but to a 20-year-old American kid it was pretty harrowing. There was talk of bombings along the border and potential border closure, and I'm pretty sure I was on the last train that got out to Austria for several days. So even though I'm in the United States now, I technically never left Yugoslavia...Yugoslavia left me. And since Yugoslavia is no longer there, I cannot go back and leave it...I am perpetually in a state where I have never left Yugoslavia.
