South Asians as Politicians in the West

What with many people with South Asian origins making it to political positions in Western countries (read UK and US), I think curbs on who can make it to the Senate are on the cards.
Imagine a situation where the US needs to decide whether to bomb Pakistan 'back to the stone age' and there are influential Senators of Pakistani (or for that matter Indian) origin among the powers that be. Don't you think the situation will be fraught with all kinds of overtones and undercurrents? Sure it will be. It is impossible to believe these Senators (or MPs) can remain totally neutral.

Bobby Jindal and Sayeeda Warsi (http://beta.thehindu.com/news/international/article429157.ece) are examples. I'm sure people very high up in the echelons of power both in US and UK (and elsewhere) are already talking about it. I'd say it is only a question of when rather than if.
