Question

Answer 1

There are many events in history that would be interesting to see if things had been different / if thing happened differently,

from the British point of view,  you got,  What if  boudcia had beat the Romans in 60-61 ad, would they (the Romans), bothered with Britain, left and not come back, or would they sent more men /reinforcements), and tried to rule it with a more iron fist, etc. then you got The battle of Hastings, what would have happened if the men,(English), on the left flank, stood firm, didn't break away, and follow the french down the hill, (possible fake retreating, down the hill), would the British be as strong as they are now, be stronger, or even maybe weaker, and not forgetting the u.s.a independence, how different if they, (the British), had won, would they, (the u.s.a), still be under the British, now that would be good to see...
