How much of the fall of the Rupee is in the Government’s hands v/s the Central Bank’s?

The Rupee (currency of India) has been falling consistently against the dollar since a few weeks (months?). Critics here and there have been blaming the government for it, but as far as I can recall, we have a dirty floating system where the Rupee varies in the limit set by the Reserve Bank of India. The cause is mostly the external shocks.

My questions are:

1. Why is it falling at such a rate? How is the war impacting it?
2. How much of this fall is the government's fault? What can we do to assuage this crisis, if it can be called a crisis?
3. Are other similar economies also going through the same?
4. Why isn't the Dollar falling (due to Trump's irrational actions)?
5. What is the worst case scenario? How should we prepare for it?
6. Any other useful information that I can have?

Note: Please do not comment political stuff and biases; facts would be appreciated.
