If you're using the Optional Cards, bid 2 Influence and put them both in Iraq.
That is probably the most common way to play right now.
However, the restriction is usually that he US player must place the extra influence where there is already US Influence. I've never seen a rule that says you can put it absolutely anywhere.
I'd have to know what was in my hand, but I'm not sure I'd put it anywhere else though.
Iran is definitely a good choice (I'm sure Michal meant Iran instead of Iraq), but I like the idea of India. Gives great access to SE Asia and India/Pakistan. I'd probably split between Iran and Pakistan if I had two, but to be honest I wouldn't want to give US more than one extra influence with this format. To be honest, I find it much better to only let US place where they already have influence. I've also never seen 6, even before optional cards when experts would sometimes bid 4 or even 5.
