Antony Polonsky observed that the attitude of the military underground to the genocide is both more complex and more controversial its approach towards szmalcowniks. Throughout the period when it was being carried out, the Home Army was preoccupied with preparing for ... moment when Nazi rule in Poland collapsed. It was determined to avoid premature military action and to conserve its strength (and weapons) for the crucial confrontation that, it was assumed, would determine the fate of Poland... to the Home Army, the Jews were not a part of 'our nation' and ... action to defend them was not to be taken if it endangered [the Home Army's other objectives.He also noted that "it is probably unrealistic to have expected the Home Army—which was neither as well armed nor as well organized as its propaganda claimed—to have been able to do much to aid the Jews. The fact remains that its leadership did not want to do so." Rowecki's attitudes shifted in the following months as the brutal reality of the Holocaust became more apparent, and the Polish public support for the Jewish resistance increased. Rowecki was willing to provide Jewish fighters with aid and resources when it contributed to "the greater war effort", but had concluded that providing large quantities of supplies to the Jewish resistance would be futile. This reasoning was the norm among the Allies, who believed that the Holocaust could only be halted by a significant military action.
