In order to learn from the lives destroyed (and lived) amid our inheritance of modern humanism and its uses of time, Almost Futures asks us to recognize new spectrums of feeling: the poetic, in the grief of protesters dispossessed by land speculation; the allegorical, in assembly line workers' laughter and sorrow; the iterant and intimate, in the visual witnessing of revolutionary and state killing; the haunting, in refugee writing on the death of their nation; and the irreconcilable, in refugees' inhabitation of history"--$cProvided by publisher. 410 0$aCritical refugee studies ;$v6. 517 3 $aSovereignty and refuge at world's end 606 $aVietnam War, 1961-1975$xRefugees 606 $aVietnamese$xSocial conditions 606 $aVietnamese Americans$xSocial conditions 606 $aSovereignty 606 $aGlobalization 615 0$aVietnam War, 1961-1975$xRefugees. 615 0$aVietnamese$xSocial conditions. 615 0$aVietnamese Americans$xSocial conditions. 615 0$aSovereignty. 615 0$aGlobalization. 700 $aNguyen-Vo$b Thu-Huong$f1962-$01605606 906 $aBOOK 912 $a996599572703316 996 $aAlmost Futures$94168538 997 $aUNISA
