Let say that a country like Iran or Nk start using BTC to finance some of their activities or organization like "alqaida" ask ransom in BTC.
The US government killed way more people than Al Qaida and Iran and many people use USD...
FYI:
While the US probably has killed more then Al Quaida and Iran, your infographic has many lies in it. Iran attacked Iraq is the easiest but there are many others.
