Set in alternate parallel universe where reality mirror ours with one big exception, the cunning dwarfs. The male adult is less than the length of an iPad but weights 50Kg, their technology is far superior than us but we outnumbered them by a factor of 10,000,000,000:1.
Set in the 21st century A.D. the dwarf already solved the dark matter and dark energy issue and also harnessing energy from quarks fusion/fission process taping into the strong nuclear force and detonate the world first quarks bomb in an underground testing facility on Mars. They have invented an ingenious way of exploiting the laws of physics governing quantum gravity and managed to weave all fundamental forces together to open a boom tube into the past and successfully fetch a family of Diplodocus into the present in order to spite human kind.
My question is if the dwarfs now possesses an army of dinosaurs spanning from Jurassic to the Triassic period, how can human wage war against these prehistoric creature assuming the dwarf already solved the "jet lag" and adaptability issue for these creature?
The victory condition is to enslave the dinosaurs and feed the dwarf to the carnivorous, vice versa will spell our demise (defeat is unacceptable).
Dwarf being more intelligent than us will teleport millions of dinosaurs regardless of size, diet, wings, etc fit tem with breathing apparatus at all kinds of power plants, military HQ, air bases, naval yards, military barracks, arsenals, communication towers and underground bunkers simultaneously and instantaneously. (1 wave per hour each facility will be swarmed with max. capped at 1 thousand dinosaurs per day.)
The dwarf will not use their tech directly against us unless all of our resistances failed meaning all of our military capabilities are compromised and the dwarf will put the remaining human populations out of its misery.
The dwarf plans to overrun each military facility with thousands of dinosaurs each equipped with an ambulatory device with two pronged attack from the inside out and encircling the entire premises.
Submarine will be chased by hundreds of Mosasaurus.
Air fields are infested with swarms of prehistoric insects and thousands of Pterosaurs ambushing landing or refuelling aircraft.
