Traded overseas possessions for arms? Errrr...by that you mean you gave away someone elses territory to protect your homeland I presume.
Sat back and reaped riches? We could have remained truely neutral as international law required and really sat back....much like the Swedes and Swiss I suppose.
Tell me about the USS Reuben James....and how those guys sat back and watched....or the other Americans in the RAF flying in the BoB wearing crab blue.
I should think the financial gain we garnered might have been offset just a bit by the investment in things like the 8th Airforce and the 82 Army Divisions we sent to Europe along with significant naval units.
But then why let facts interfere with a good rant I suppose.
