Most modern users of English would write:
"If the Wind succeeded in doing that ti would be stronger . . .
The "proper" form, however, would use the subjunctive for "to succeed," followed a conditional of "to be":
"If the Wind succeed in doing that it would be stronger . . . "
Help yourself, one is correct based on current usage, the other is correct based upon an anal dedication to "the rules."
Your construction assumes the subsequent failure of the attempt before it has actually been established.
I didn't get you very well Craven.
If I were you, I'd write:
If you understand this post you will not need more examples.
If you now understand this post you will no longer need more examples.
My reason for this is: your understanding it or not is unsure at present. If you understand it now, AND THEN (time goes from now to future) , you'll not need more examples.
Of course the answer
"If the Wind succeeded in doing that it would be stronger . . . " is perfect.
Because "would" is omnipotent?
