In the midst of the holiday season, on December 28, 2012, President Barack Obama signed into law the "Countering Iran in the Western Hemisphere Act of 2012." This Act seeks to initiate a whole-of-government approach to what looks to be an increasing threat to the United States, and by extension to Canada as well. Canada is no stranger to the Islamic terrorist threat. The millennium bomber -- Ahmed Ressam, the Toronto 18, and Omar Khadr, among other high profile cases, have brought radical Islam to the forefront of Canadian national security. Closing the embassy of the Islamic Republic in Ottawa last year shows that Minister Harper is serious on his promise.

Friday is the Global March to Jerusalem (GMJ) -- the sole purpose of which is to confront and provoke the Israelis, with the hope of eliciting a violent reaction and creating a public relations bonanza. Let there be no doubt -- even Iran's terrorist tentacles are all over this march, down to the very last detail.

This Iranian assassination plot is a major escalation in Tehran's war on America. Because Iran has never faced serious consequences for its hostility, it is now willing to run a lethal operation on American soil. The operation was likely authorized at the highest levels of the Iranian government.
