i would be a amazing leader for a nation, simply by the fact i would put my nation first. First order if i where in charge would be a complete removal of all foreign aid, only maintaining what is necessary to keep key allies and trade partners. Harsh sentences for violent crimes and form separate prison for non-violent offenders, non-violent offenders can be rehabilitate but violent offenders must be kept locked up. Impose strict migration laws, no-one enters and no-one leaves beyond businesses travels or tourism, also start sending away non-natives that posses no true value to society.
Ban on hardcore pornography, only allowing soft-core material to be legally produced, imposing harsh sentences on those that smuggle or produce hardcore porn. Fund anti-alcohol and anti-narcotics programs. Anti LGBTQ+ laws. Promote anti-religious sentiments. Promote militant Nationalism. Fund programs for men that have been or at risk to end up as rejects left out of society.
I would do far more but this is the first things that comes to mind.
