To beat Fernando...
You will need team orders.
Karma is surely a biatch 

Will it be Red Bull or McLaren ordering the two consecutive Alonso DNFs?
You might say that you need team orders, but that's wishful thinking on your part just like my wishful thinking is blue smoke out of the Ferrari engine.
That's a tough one. I dont think mclaren would do that... so maybe Red Bull. RB can make it look less conspicuous hehe
But no, I think they dont need to be so harsh. All they need is to make it easier on themselves.
But definitely if RB allow their drivers to race itll be much much harder. Mclaren NEED to support Lewis, and RB are on the thin line of is it better or not... perhaps after Brazil they'll have a clearer situation, depending on how Alonso and their drivers do.
Brazil is not a bad track for Red Bull, but I think Ferrari can at least split the front row. Then it will all depend on those engines........... They should fit some sort of fireworks, so if Alonso's engine blow they make a little firework spectacle. hehe
I know the feeling of NEEDING to support one driver when that drive is the only one in contention, and McLaren are there right now, even if Button is mathematically still in it... but I haven't gotten a really convincing argument yet as to how it's not possible for a large team like McLaren not to do both. And I mean REALLY helpful things, not just stacking pit stops or having Jenson do some testing of parts or try out wets before Lewis or somethign like that.
From a purely logistically capable argument, a LARGE team like McLaren or Ferrari can really support BOTH drivers. I mean to maximize their WCC chances, McLaren would be crazy not to want both of their drivers scoring maximum points since they realistically have a better shot at that title than the WDC title. I don't think McLaren would have difficulty in developing two new upgraded parts for each driver,it's not like we're talking HRT and limited resources.
I don't really see how a driver can actually help the other outside of obvious moving over to let a team mate pass or driving a really wide car if they happen to be in front of a rival contender.
The more I think about it the crazier it seems that Red Bull didn't wrap up both championships two races ago!
