This is pedantic, pointless and wrong.
Modern uses of the word are simply wrong and nonsensical if you understand that "deci" means 10, which should be obvious to any competent English speaker who knows of the word "decimal" and understands our numbering system.
The only other entries in the disambiguation page are about signal processing and a comic book.
Oh, and that is not to mention that the original meaning of "decimate" was "tithe," not "kill on in ten soldiers."
"The word decimation is derived from Latin meaning "removal of a tenth"."
I like how buddy proves to you he's right, and you have the gall to act like you're right.
Besides, this argument is over pedantics. My original comment stands. China is weak compared to US. No war necessary, restructuring in favour of US WILL TAKE PLACE.
