It is not as if

[nickkk]

Warnings ignored
It is not as if we have not had enough warnings. I have a pile of reports and surveys in front of me which make the connection. It is strongly made in the Brundtland report, Our Common Future, of 1987. It is there in the 1992 Canadian Science for Peace study of the impact of militarism on the environment. The Swedish group Co-operation for Peace made the connection in their Military Threat to the Environment (1992). Only last August the International Peace Bureau produced a comprehensive sixteen-page study which covered all the poverty / environment issues.

It is not as if означает "нельзя сказать, что мы не (получали предупреждений)?"

Русский (синоид.версия)

N.B. хоть с запятой после "то" перед "чтобы" и не согласен...но из песни слов не выбросишь))
