The simple fact is that countries always act according to their interests. The US flipped flop on certain issues because different situations demanded different approaches. This is true for all countries even India. Indians like to promote India's alleged fundamental distaste for intervention of other countries affairs (non-interventionist policy) but has intervened herself in other countries when her interest demanded it. The only reason why India has limited history of intervention is not because it does not like to intervene, the reason is that it's interests do not yet cover the World or half of it. Just wait when you become the absolute master of South Asia or Asia... and pigmies like Sri Lanka wants to assert their autonomy to the distaste of the leaders in Delhi...
Sure. All countries act in their interests. Some countries may be more brutal than others. Some countries may be more gentler than others. But, at the end of the day, all countries act in their interests. Ideally, the brutal countries(generally, referred as rogues) most be curbed. Also, there are certain accepted ways and some unaccepatable ways. Dropping atom bombs comes under the second category for most people. Do you want all us to make exception in US' case?
Anyway, I dont object when you say that US did whatever it did in its interests. I object when you say that everyone must accept it as the right thing to do. There is a difference between the two stands.
BTW, you're still avoiding the issue of what if you were in his shoes?
Its a hypothetical question. And I replied by giving you another hypothetical situation: Imagine yourself as Japanese Ruler or Japanese citizen.
If you insist on you hypothetical question, then my answer is: I dont know what I would have done if I were in Truman's position. Maybe I would have done the same. Maybe I would have avoided such a dastardly act and tried to find other ways. Perhaps, I would have considered losing the battle more honourable than killing so many civilians in deliberate and potentially unstoppable destruction. I dont know.
But I do know that I am not in Truman's position. So, there is no need for me to imagine myself in Truman's position just as I dont need to imagine myself in Osama's position and justify his actions based on his needs and aims.
I think the unsaid point is that you like to blame US for the ills happening now in that region. You'd even throw out the window the clarity of the decision made by them in A-bombing Japan just to ram the point that the US is the A-hole of the World: "just let Iran get those nukes (however morbid is the idea) because US is the one leading the effort to stop it..."
You are making many conclusions in a mistaken manner.
Is Iran going nuclear good for India? No.
Is Iran going nuclear good for US? No.
Is Iran going nuclear good for Iran? Yes.
Is it the worst thing to happen in the world? No.
Pakistan is already a rogue nation with nukes. And the best part is that it is kept afloat by US funds because they claim that nukes will fall into the hands of terrorists if they dont keep them afloat. Remember, US turned a blind eye when Chinese transferred the nukes to Pakis.
India's threat from paki nukes is far greater than any potential nukes of Iran.
Should the US try to stop Iran from acquiring Nukes? Yes.
Should India support the effort? Yes, but without antagonizing Iran too much.
Is US the conscience keeper of the world? No.
Is the US protector of righteous countries and punisher of wicked regimes? No.
