Should one use "the" before government?

Bringing change in government and its policies"

For a country's government's policies, should one use "the" before country name only for US and not India?

"Studying Indian government's approach and the US government's approach"

Typically there is no article used before the noun "India" (e.g. he went to India) but it is used before "US" (e.g. "the US").

Should "the" be used before "India's government" or "india's policy?"

It seems that the answer will depend on whether the definite article is modifying the definiteness of "India" or the "government/policy." For the former, there will be no "the," unlike the latter.

Thoughts?
