There is no longer time for statements like "if only" or "we can't." We must and we will succeed. The only question now is how and when. I believe the time is now.
At the start of the American Civil War, the battle of Fort Sumter ended after the Confederates under Beuaregard bombarded the fort with 4,000 shells. The first causualty of the Civil War died when his cannon backfired.
