The West's double standards are not restricted to China and Nigeria. The decade-old wars in Iraq and Afghanistan have cost the lives of hundreds of thousands of civilians, but the mainstream media outlets in the US have largely ignored the tragedies and focused on the loss of their own troops.

If the number of civilian casualties is a measure of the intensity of a terrorist attack, tragedies like the Sept 11, 2001, attacks have occurred multiple times in Iraq and Afghanistan. But the Western media don't seem to care much about them.

Some Western observers have even found excuses for West's inadequate response to the terrorist attacks in Kunming on March 1 last year in which 31 were killed and 141 injured. But by failing to immediately condemn the attacks against innocent civilians in Kunming and Xinjiang, these people have by default condoned the action of the perpetrators.

It is true that terrorists in the eyes of some could be freedom fighters in the eyes of others. That is why Osama bin Laden was a freedom fighter to the US in the 1980s but a top terrorist in the 21st century. And Nobel Peace Prize winner Nelson Mandela was still on the US terrorism watch list as late as 2008, years after stepping down as South Africa's president.

There is no doubt that the US and its allies have failed miserably in their "war on terror" despite the more than 1,000 air strikes launched against the Islamic State group. In spite of the heavy bombardments, we have seen terrorists gaining strength and spreading their tentacles to more areas across the world.

And the Western world responds to this deadly threat with double standards.
