American Samoa's member of the US congress says the decision to send 30,000 more US troops to Afghanistan leaves serious questions unanswered.
Congressman Faleomavaega Eni Hunkin says President Barack Obama's speech to announce the troop buildup was comprehensive.
But he says there will be a mixed reaction from the Congress to the announcement.
"The bottom line is who's going to pay for it. That issue was not discussed in the President's speech, but there are estimates already been floated, the fact that it's going to cost about one billion dollars for every thousand soldiers we send to Afghanistan."
Congressman Hunkin says many liberal democrats had wanted the US to pull out of Iraq and Afghanistan.
He is questioning how the US can be successful in Afghanistan when 120,000 Russian troops failed to take control there.
American Samoa has one of the highest per capita rate of soldiers in the armed forces of any US territory or state.
