Hamas launched a bunch of rockets from Gaza in a surprise attack on a holy day and then put ground fores in. This attack killed at least 100 Israeli civilians (Israel is also claiming near 1000 more injured) and has captured more.
Israel is of course going to retaliate and try and destroy the sites (surrounded by civilians since Hamas is known to try and use sensitive civilian locations as shields) and probably occupy Gaza in an effort to keep these rocket attacks from happening. Which will cause more Palestinian casualties, thus the cycle continues.
They're not able to keep up with the breeding in Texas, and there's even helicopter tours where you can try and wipe out whole herds at a time.
