IMO, from the Indian perspective, a strong America that can stand up confidently against China is a must for the next century. China will become the biggest economy sooner or later and that's is when no.2(US) and no.3(India) have to work together to make sure that the global order stays open and democratic.
However, what GW Bush did by his misadventures in Iraq and bungling of the right war in Afghanistan is that he brought the day China would over take America from 2040 down to 2020. And if any of the Republican candidates who like to play to domestic politics and trump unilateralism as a version of Bush 2.0, then they might even bring that down to 2015. I don't want US to get anymore weaker on the International arena which was what Romney and in particular Santorum not to mention Gringich's policies would do. Ron Paul does not count at the moment as he is not a contender really.
And on Israel, Obama has done more for Israel than any US president in history. And that is a paraphrased quote of Defence minister Ehud Barak as well as Shimon Peres.
