no need to wait for next 4 years.
US is lumpar 1.
fact - defence budget 2016
USAss $601 billion
Russia $84.5 billion
chinks $216 billion
nihonji $41.6 billion
ah-neh $50 billion
the only advantage USA has left is its big ass millitary,but a strong millitary depends on a strong economy,without money u have nothing.already america's debt is the biggest in the world at 19 trillion dollars and their deficit is humongous,2.4 trillion a year.unless they intend to become like russia,which has a powerful millitary while the people are poor as fuck and suffering,they will be forced to cut back on their military spending and that will be the end of that.china's economy will continue to grow while america's continue to shrink.
at the beginning of the 1980s,under deng xiao ping's open china policy,USA's share of the world economic gdp pie was 40 percent......today it has shrunk to 22 percent and falling....the white world is getting poorer and poorer relatively.
