The deep ties of heritage and blood between Canada and Louisiana magnify the impact of two terrorist attacks in our northern neighbor.

In both cases, radicalized Muslim converts struck at soldiers. One victim was killed and another injured in Quebec. A soldier on guard at the National War Memorial was shot in the back, and then the gunman sprayed bullets around the offices of Parliament in Ottawa.

Both assailants were killed, the latter apparently by the sergeant-at-arms of the House of Commons, whose duties were usually more ceremonial; he ended up, as so many others civilian and military before him, on the front line of an international war on terrorism.

The concern and sympathy of the American people was promptly expressed by President Barack Obama. The people of Louisiana are proud to be associated with those sentiments for our cousins to the north.
