Read the following passage carefully and answer the question that follows.
Subhas Chandra Bose, one of the most prominent figures in India's struggle for independence, left an indelible mark through his revolutionary ideas and leadership. Bose's political journey is intrinsically linked with the Indian National Army (INA), which he led to fight against British colonial rule.
Bose, initially a member of the Indian National Congress, grew increasingly disillusioned with the party's non-violent approach to achieving independence. Believing in a more proactive stance, he sought the support of foreign powers to free India from British rule. This quest led him to Germany and later to Japan, where he took command of the INA in 1943.
The INA was primarily composed of Indian soldiers of the British Indian Army who had been captured by the Japanese in the Southeast Asian theatre of World War II. Under Bose's leadership, the INA adopted the motto "Jai Hind" and fought several significant battles on the Eastern Front, notably in Myanmar (then Burma) and the Indian frontier.
Subhas Chandra Bose's rallying cry, "Give me blood, and I will give you freedom," motivated many to join the INA's cause. Despite its ultimate military defeat, the INA significantly impacted the Indian independence movement, inspiring a wave of nationalism and contributing to the British decision to leave India.
Which aspect of the INA's formation and operations demonstrates the complexity of international alliances during World War II?
