Mika's father, Zbig was a young boy/teen during Hitler's reign. Believe he had a background of helping Nazis locate other Jews, like Soros. He basically recruited, trained, handled Osama bin Laden. HIS father was the Polish Ambassador to Germany in early to mid 1930's, then went to be Ambassador to USSR for 3 years. Left there to be Ambassador to Canada and 2-3 weeks later Poland was invaded by both Germany and USSR. Most likely - Fuckery from Mika's Grandfather! Seems suspicious.
