Regardless of what the UK does about the team, it's backed by the Malaysian govt. Even if they were HQd in England, it's being pushed by them.
From the official Lotus Racing profile @formula1.com:
Company Name: 1Malaysia F1 Team Sdn Bhd
Team Name: Lotus F1 Team
Country: Malaysia
Team Principal: Tony Fernandes
A partnership between the Malaysian Government and a consortium of Malaysian entrepreneurs, 1Malaysia F1 Team returns the Lotus name as a constructor to Formula One for the first time since 1994. The team will initially be based at the RTN facility in Norfolk, UK, some 10 miles from the Lotus Cars factory. A 50,000 square foot fully equipped facility, RTN was built by Toyota for its initial Formula One programme and then used by Bentley for its successful Le Mans programme.

Regardless of what you classify as "support of a nation", I'm sure there's been no team that exemplifies that expression like "Lotus" Racing as of now. I mean, I don't even know how to respond to that; what else do you need to see before you're convinced? Not only is Lotus backed by a company with government ties, the actual name of the company is 1Malaysia! Lotus Racing is a government initiative! It doesn't matter that you said the people of Malaysia don't support it; in the context of senamic's post, neither did NASCAR USA support USF1. So again, where do we get off saying USF1 had the "support of a nation" when it didn't have neither a) political or b) demographic support?
I don't know in who's book Argentina (which he never mentioned) qualifies as a "powerful nation" (direct quote). My point still stands.
