Were NOT OUR RULERS TOO Naive/ Moronic&SHOULD NOT OUR RULERS/KINGS HAVE developed AN ENTRY VISA/PERMIT system FOR foreigners & PREVENTED Entry OF Foreigners USING FORCE FOR PAST 2000 Years?

As an  indian  Research scientist with an  indian  passport, I  had to answer   hundreds  of  questions& to pay  good  amount of money  as  entry visa  fees  for  securing entry visa or  entry permit  to  developed  or rich  countries, including entry to  english soil, despite  being fooled cheated  & looted  hundreds  of  trillions of  dollars  of  our wealth for  over  300  years,And worse , despite being an invited speaker way back in 1976 instructed by my professor Maurice Panigel to explain to a selected audience in department of Chemical Pathology of English professor Sandler at Queen Charlotte Hospital in London the intricacies of a revolutionary human placental perfusion technique , I was confronted by a rogue Young & muscular englishman & a staff member of Professor Sandler’s research team on the evening of my presentation and threatened to cut my limbs if I dont leave english soil within 72 hours, I was compelled  to  ask the  question,  why  our  kings  ruling nearly 500  kingdoms  of our  continent  never  realized  the  dark truth  that  visitors from  europe  or  central  asia  dressed  or disguised  as  traders  had an  ulterior  wicked agenda  to  snatch power  and to loot the  wealth  and were  dacoits  with a  fake   name& fake identity ! Yes  it was  guns, canons& mass murdering weapons  that  were  ruling the  world then  as  is  the  case now  and universal  brotherhood  & love of  humanity  , non-violence  etc  were  just fooling, cheating & looting  slogans  then as is the  case, sadly now too! What a  Farce!
