Myanmar's Suu Kyi's defense of army puzzles former admirers

What drives Aung San Suu Kyi, the leader of Myanmar who this week defended her country at the International Court of Justice against charges that it carried out genocide against its Muslim Rohingya minority?
There are signs that she shares the paranoia of many of her predominantly Buddhist countrymen about Muslims, most recently evidenced during a visit with Hungary's right-wing leader, Viktor Orban, in which the two issued a statement saying that "coexistence with continuously growing Muslim populations" posed a challenge for their respective countries."
By representing Myanmar at the International Court of Justice, she draws upon her aura as a champion for the Myanmar people (as vague as that might be) and as a politician. If she is seen to be defending Myanmar in the eyes of enough of her supporters (and it is read that way by many, as far as I can tell) then it will attract votes in 2020."
