The world is at war with an hostile alien race. This species invaded earth a few decades back, and forced the governments of the planet to unite under a single federation. This world government is similar to the EU and retains some of its democratic institutions, but with more centralized power. This was done to combine resources and to make fighting back more effective. Unfortunately, the war is going badly. People are being slaughtered in the hundreds of millions, genocide on a scale unprecedented in human history. These aliens are committed to exterminating the human race for unclear reasons. Trying to reason with or understand them has failed, and the world government has resigned itself to total war. In these circumstances, the human race has just barely managed to hold on.
A secret organization within the government has managed to develop a weapon referred to as a geneseed. It is an advanced form of genetic engineering that turns humans into supersoldiers. People who are implanted with the seed transform into beings similar to the demigods of mythology. They are able to move at incredible speeds, and have the strength to lift dozens of tons. They also gain a host of other abilities, including increased intelligence, heavy resistance to weaponry, and heightened senses.
These abilities come with a cost. The geneseed can only be implanted successfully in children between the ages of 10-16, with anyone older dying horribly from the process. These child soldiers grow and mature at a quickened pace, and have little to no memory of their former life. Their emotions are suppressed due to the strain of the change on their bodies. They are then indoctrinated by the government to become the perfect weapons, killing when necessary and obeying orders without question .
The government is considering mandating this policy, but want to sell this program to the public without too much resistance. One idea is to treat the parents of said child as saviors, honoring them as heroes doing their duty to save their species. Parades and celebrations are made in their honor to acknowledge their sacrifice. Another is to offer them lifetime privileges, such as tax reduction or free schooling for their other children, to cash grants, to other monetary benefits.
Would these steps the world government is taking be enough to sell a modern public to support this policy?
