Whether India should be with the U.S. against China is a complex question with no easy answer. There are many factors to consider, including India's own national interests, the evolving strategic landscape in the Indo-Pacific region, and the relationship between the U.S. and China.

On the one hand, there are strong reasons for India to cooperate with the U.S. against China. The two countries share a number of common interests, including the need to ensure a free and open Indo-Pacific region, to counter China's growing military power, and to promote economic development. Additionally, the U.S. is a major source of military and economic assistance to India, and the two countries have a long history of cooperation on a range of issues.

On the other hand, there are also risks associated with India becoming too closely aligned with the U.S. China is a major trading partner of India, and a close relationship with the U.S. could jeopardize those economic ties. Additionally, China could view an India-U.S. alliance as a threat, and could take steps to counter it.

Ultimately, the decision of whether or not to cooperate with the U.S. against China is a decision that India must make for itself. There are no easy answers, and the best course of action may vary depending on the specific circumstances. However, it is clear that India's relationship with China will be one of the most important factors shaping its foreign policy in the years to come.

Here are some additional points to consider:

• India has a long history of non-alignment, and has been reluctant to join any formal alliances. However, the rise of China has forced India to reconsider its foreign policy options.
• The U.S. and China are engaged in a strategic competition for influence in the Indo-Pacific region. India is a key player in this region, and its cooperation with either the U.S. or China could have a significant impact on the balance of power.
• The U.S. and India have different strategic priorities. The U.S. is primarily concerned with containing China's rise, while India is more focused on economic development and regional stability.
• The relationship between India and China is complex and has been marked by periods of tension and cooperation. It is unclear how the relationship will evolve in the years to come.

Given these factors, it is likely that India will continue to pursue a policy of strategic autonomy in its dealings with the U.S. and China. India will cooperate with both countries where it is in its interests to do so, but it will also be careful to avoid becoming too closely aligned with either country.
