The cost of space exploration is considerable ... but the cost of banging up ISIL which Australia has just committed to, is quoted at around $500e6. That would translate to a pretty serious space project.
Which is preferable ... well I think an off-planet program would generate more hope and positive outcomes than a war against another country.
Add to this the known risk of extinction events on earth from asteroid, and being able to move off-planet begins to look quite prudent, as well as interesting and exciting.
Is it worth the cost ? I think so.
