If we apply the same standard for the word 'genocide' to the results of the foreign policies of the US and UK with regard to Muslim countries as we are using to define genocide in Sudan, then we can definitely call it genocide.

If we can use the term genocide to describe the actions of the people who set up the conditions in Rwanda that resulted in genocide (without necessarily doing any of the actual killing themselves), then we can most definitely apply the term genocide to the actions of the US and UK that have resulted in close to a million people being killed in Iraq and Afghanistan since the US and UK invaded and occupied those countries. And genocide also applies to the systematic destruction of the culture and society of a group of people as well. The actions of the US and UK are responsible for the destruction of the Iraqi society and ancient as well as modern culture.

And it's ongoing because we can expect the governments of these two countries to expand it to include other Muslim countries in the not too distant future.
