I'm not at all surprised that you have to ask.
The Nuremberg War Crimes Trials set the standard. The US has broken that standard, ie. every US president since WWII has been a Class A war criminal, and if Nuremberg were followed, they would all have hung. Does that give you some inkling of how evil the US has been.
You're right. It's the same old garbage that has been propagated since the US launched two illegal wars based on the lies of 911.
People who repeat this just don't have much upstairs. A sane, rational person can easily see that these are silly, goofy lies. Who has done the infiltrating and invading, who has killed millions compared to tiny numbers, who has committed the war crimes, who has committed the terrorism?
Who has created the refugee problems?
