No, there is no reason for that. The offense of the Nazis esp. is unpardonable. Let us be clear on one thing. It is not Nazis that helped Subhas. It was Adam Von Trott and his India office of the foreign Ministry. Adam Von Trott zu Scholz was an anti Nazi. He belonged to the Kreisau Circle, who wanted to assassinate Hitler and Trott was executed in the 1944 conspiracy of Count Stauffenberg. The Nazi leadership initially treated Bose as an Indian Nationalist who they could make use of if their plan of Operation Tiger was successful. But after Russian debacle they realized the worth of Bose, they realized his military superiority over Hitler’s plan. Whatever Subhas Chandra Bose had given as a plan to Nazi leadership in the second world war they disregarded because Hitler actually had no plan to decimate Britain. His plan from the beginning was to enter into a compromise with Britain and decimate Russia. So Nazis supported Subhas merely because they wanted to take advantage of him once they had flattened Russia, to conquer Afghanistan and later India. But soon they realized that they were up against a far superior person, who would not play their game. Subhas was neither Grand Mufti of Jerusalem, nor PM of Iraq Rashid Gaylani in exile. When they realized it, as a token of respect they accepted his plan of sending him to the far East and provided a U Boat for the same. They never used the Indian Legion for direct warfare, only for defence. Himmler tried to incorporate it half heartedly into Waffen SS at the fag end, but did not press for that when the Indian soldiers did not agree. Subhas repaid the German debt in full/partial from Singapore, from the contribution of the Indians. He had no obligation towards Nazi Germany. It is to be noted that Mussolini respected Subhas Chandra Bose, but not Count Ciano who had set up a fundamentalist like Iqbal Shidai to work against India's interest. The point is, Fascists and Nazis wanted to make use of Subhas Chandra Bose in fulfilling their interest, but they failed and while some of them accepted his superiority and worth, others became his bitter enemy. There is no need to respect them by forgetting their atrocities for any little help that they provided. They were driven by a purely selfish agenda.
Similarly Japan trued to use Subhas Chandra Bose and they realized their mistake very soon. Hikari Kikan was the first casualty. In every respect interest of India and Azad Hind and the Indians was Subhas Bose’s first priority. He was not Dr. Ba Maw, nor the President of Philippines, nor to be cowed down by the personality of Tojo. That was why he was extremely respected by Premier Tojo and Count Terauchi, people who mattered. He was hated by the Japanese bureaucracy and some leaders of the Imperial Army (like the Kikan leaders, including Yamamoto) because they could not align him to Japanese imperial interest. It was unbelievable to Japan, who had a perception of superiority among Asian races, that they would have to follow the dictum of an Indian, from a British colony. Subhas pressed for complete freedom of Indians under Japanese, Indians would be under Azad Hind Government - something Japanese never allowed in any of their occupied territories. Japanese Army, esp. Kikan wanted INA to be stooge, a mere flag bearer of Japan, which Subhas vetoed and Subhas Chandra Bose ensured that INA was the key leader in leading the attack on the British Army in India. An incompetent Kikan in charge of reinforcement, messed up and INA paid the price. Netaji was livid. He made sure that Hikari Kikan was removed and Azad Hind had its own Supply Chain base. Japan had no intention of creating and supporting an independent Indian Government. But because of Netaji’s influence Tojo agreed. Japan was never in favour of a strong and independent Indian leadership, but like the Nazis, they found that they were no match for Bose. Japanese Imperial Army had a fair number of British stooges as well, who collaborated with the British and American forces in the very end of the WW2 to protect their own interest. True patriots like Tojo, Terauchi. Hachhiya, Tada, Shidei were on the side of Subhas Chandra Bose and it is them that we should respect, just as we should respect Adam von Trott, Erwin Rommel and others who were German Nationalists but fought the Nazis.
