They wont switch to Euro, hasnt happened, EUROPE DONT HAVE THE MILITARY MIGHT AS YET OF AMERICA.
OIL is traded in DOLLARS. Dollar is accepted worldwide NOT EURO.
EUROPE itself is dependent on USA for security and nuclear umbrella, as of now they cant do on their own. RUSSIA bullies european countries even today and gets very high prices for its gas. European Union has to develop military muscle to defend itself against RUSSIA who are increasingly assertive. UNTIL THEN DOLLAR will rule.
USA invests billions in new weapons and systems, When rest of the world is making missiles, USA is investing hugely in laser weapons which no missile can match. Laser travels at speed of light.
China is all big nothing inventive or innovative. just a big mass. CRAP aircraft or weapons.
