The USA didn't rush to machine gun nests. Most Americans wanted nothing to do with ww2. FDR dragged them kicking and screaming.so you're ok with a loss of life when it knowingly could have been avoided? (Again this is only under the hypothetical that intelligence knew of a real and credible threat)
What you write really highlights the decline of our nation. The WWII generation, when faced with a threat, rushed machine gun nests to protect and secure liberty.No one asked if we were "ok with the loss of life," it was part of our culture that liberty was worth dying for. Now we entertain surrender to a two bit nest of thugs and gangsters for fear that they might engage in terrorist acts.
After the Japanese bombed Pearl Harbor Americans were standing in line to enlist. I don't know who told you otherwise.
