> And who better to know about expansionism than Indians? We have been colonized multiple times in the past.
Sure, we can agree that USA's invasion of Iraq and Afghanistan was not "colonization" technically, in the 1800s sense of the term.
However, what else would you call all out war, military occupation, hanging the president of the country, etc.? BTW, occupation continues until this day, in both of these nations.
> Manifest Destiny is a cultural thing in the United States. It is not official State policy.
Have you read about the history of the U.S in the 1800s? Manifest Destiny may not have been written into the constitution, but it was absolutely the policy of many leaders of the U.S in that era, and calling it "a cultural thing" actually dumbs down what is an extremely powerful idea behind the forming of the U.S as a nation.
> We have a similar cultural quote in India called "Akhand Bharat" where we wish to go back to the time where Bharat was one territory and not divided into Pakistan, India and Bangladesh.
China has a similar idea with the "One China" rule, and how it basically does not consider Taiwan to be it's own nation. Except, unlike India, it's quite clear than China is willing to invade Taiwan at some point in time (unclear when, but the tensions will never cease).

The 1800's style colonization is certainly no longer present, but a variation of it is certainly present, and usually military invasion is not the main tool to achieve domination (however, in the case of Iraq, Afghanistan, it clearly was).
