Which was very bad move. If people act like thugs, odds are they are going to be regarded as such.
It might also be a factor that India has nukes... at least according to the pakistanis I've spoken to. Iran doesn't enter the equation. It is all about Kashmir. Blame the British
One of my best buddies during university years was a deserter from the Iranian army during that war. After two years at the front for Ayatollah and country, he left for northern Europe, developed a liking for danish girls, pork and beer (poor sucker ended up married with kids, slight beer belly and love handles). He rarely ever spoke about the situation in Iran and what little he did tell was scary. He was worried about the fate his family, him being a deserter, hoping that one day he would be declared officially "dead".
