Wikipedia describes Lee as such: "Lee oversaw Singapore's transformation into a developed country with a high-income economy within his premiership. In the process, he forged a highly effective, anti-corrupt government and civil service. Lee eschewed populist policies in favour of long-term social and economic planning, championing civic nationalism through meritocracy[3] and multiracialism[4][5] as governing principles, making English the lingua franca[6] to integrate its immigrant society and to facilitate trade with the world, whilst mandating bilingualism in schools to preserve the students' mother tongue and ethnic identity."
That's a forward looking vision, not a backwards looking vision like the "Palestinian cause" that seems to end with restitution.
Would any politician with such a vision like Lee's even have a chance with Palestine's electorate? No idea, elections were last held in 2006...
