Famine will be a major incentive for people to take the mark of the beast, but it won't work on everyone. There will be people who are not starving, whether they are farmers, preppers, or what. So the second major incentive will be the plague. This will have to made in a laboratory and the government will need the cure so that if you want the cure you need the mark of the beast. Also, this can't be like Covid19, it will have to be something that people can see you are sick, something like Ebola. Imagine they cross Ebola with pneumatic plague. When people die it is horrific and they are extremely contagious. Now if you refuse to get the vaccine you are threatening the lives of others. But this can't be isolated in Siberia or the Congo. No, an airplane landing at a major international airport in which everyone on the plane has died from this, that would completely terrify the whole world. I am thinking this time it would have to be in Europe for this event. Finally, war is also a great way to get the whole population under control, justify censorship, concentration camps, etc. But they are going to need to make it very clear that anyone who is a traitor will be executed by a firing squad. Make the executions public, live stream them, just like we will ultimately see with the two witnesses.
