I have a friend who meddled in drugs as a young man. He was caught trying to import the stuff for his own use, he says, as he was an addict. He was convicted and spent several years in the slammer.
Every time I travel abroad, and I have done frequently over almost 40 years traipsing after the last 10 Prime Ministers, I think of him back in New Zealand. His drug trip was the last time he was allowed to leave the country.
I now have a little more empathy for him. I've been grounded, not for committing a crime but it seems for visiting Iraq with John Key to visit our troops in Camp Taji three years ago.
Filling out a visa form to have a stopover in Los Angeles for two hours on the way to London I had to declare I'd been to Iraq, a number of rogue countries were mentioned, and the box had to be ticked. I had no choice, the Iraqi visa was in my passport.
There was no explanation for the "Travel Not Authorized" response to my application but officials tell me alarm bells sound in Washington at the mere mention of that country, such is the paranoia there.
