> I know that attributing to western countries the responsability for any bad thing happening in this world is a common reflex

You can’t gloat that the sun never sets on your empire and then absolve yourself from responsibility for events that you had a heavy hand in influencing. Regardless, if you think the article is wrong, your point would he better served by providing examples of where it’s wrong and stating why.

How many years does it take for that influence to expire? In 40 years many/most of the people involved in the old system aren’t even alive anymore.

That would be like blaming me for the Gulf War when I was in diapers.
