Bullshit he can't, if he really is that smart, it's politics 101 for any generation that isn't massively-retarded like the current one is:
Leftist progressives hold power for a long time, they fuck shit up hardcore, everything takes a cannonball into the trash heap because of their actions.
People get sick of it, and give the rightist traditionalists their votes instead, because it's clear the lefties are a no-go now unless you want everyone to die, and at worst the right will be only slightly-better so it's a worthwhile gamble.
Rightist traditionalists get into power on popular vote, and start fixing the shit the lefties fucked up in the name of "muh equality", which unsurprisingly takes all of 5 minutes in the hands of someone sane and competent, unlike lefties who took decades to do basic shit-ruining because they're useless dumbshits.
Everyone is happy with the traditionalists in power for a while, until enough time passes that the kids don't know how the traditionalists saved their elders' asses from a communist nightmare world, and naively vote for the progressives because they have a good-sounding spiel of lies about equality and how the traditionalists are oppressive geezers.
Progressives get power once more. Jews eagerly rub their hands while masturbating into a pile of golden shekels, and prepare to really get started wrecking shit yet again. Rinse and motherfucking repeat, ad infinitum.
Also, in the case of extreme Jewing like Weimar that destabilizes things too heavily for the cycle to continue normally:
Progressives hold power unopposed due to apathy/rigging for so long, they get to institute every last retarded, suicide change they could ever want.
Society collapses under the weight of all this stupidity, and everyone's finances hit Zimbabwe levels of shit, causing mass starvation and other mass suffering.
"Far-right" (traditionalist, but fucking pissed in addition to normal traditionalism) leader shows up, and promises to not only un-fuck everything, but also to root out the source of the problem and deal with it.
Leader wins the vote by a landslide, and immediately names the root of the plague with clear evidence and conviction, which gets the people to believe him wholeheartedly rather than dismissing him, and efforts to cleanse this font of poison plaguing society go into motion.
A whole bunch of kikes wind up either riding out of town on free transportation so outsiders can deal with their useless asses instead of the nation while making them no longer a problem in-nation, or are masturbated to death with needlessly-complicated machinery, depending on which side of the story you're inclined to believe.
Neither case is a particularly-complicated or hard-to-comprehend series of events, which makes me wonder if either Hawking is a complete retard riding on fame, or if he knows damn well what's happening but is smart enough to not give away the course of events to the drooling, slack-jawed liberals begging him to save their stupid asses. I'm inclined to believe it's the latter option, since it'd be in-character for a massive genius to recognize getting smart and strong White men who aren't cucks into power benefits everyone (and especially him, i.e. Third Reich science programs), while letting women take power is pointing a loaded gun to everyone's head while the one holding the gun lacking any form of trigger discipline.
