I don't see why these attacks on unarmed Australian civilians have anything to do with the defensive war Israel waged against Gaza, while the Israelis metaphorically kept one hand at their side.
Claims of genocide are wildly out of proportion with the effort Israel has gone to, to limit the casualties there and with genocide the population goes down, not up !
Back to Australia, these were the evil attacks by two people who had a hatred for their new country, though like all of these people, they only consider the hole they came from with it's dark age mentality their home.
Their favourite targets always being those without means to defend, as these warped prople attack and kill as they did in Paris at a concert, and again in Manchester against a hall filled with little girls.
No excuses for this, these Islamic terrorists are evil.
Only one real way to stop these islamic terrorist attacks and that's mass deportation of this religion back to their homelands before much more of this happens. Because it will. Violence to intimidate, to control, to conquer, to occupy is their aim and Jews are only the first target, atheists, Christians, Hindus, Sikhs, Buddhists and everything in-between are all in their sights be they straight, homosexual, or identify as a cat !
Wake up and face the facts.
