And yet, Hamas is an Israel-created problem, as if Britain had funded the IRA and ensured its competition with more moderate factions.

That doesn't change any aspect of the problem. Though I wouldn't be surprised if the IRA got funding from the Labour Party.

"The most heavily-defended border in the world" was also overwhelmed by an intrusion of paragliders, motorcycles, and bulldozers lasting over six hours without a meaningful response.

Don't underestimate your enemies when you have static defenses. You should read about the Yom Kippur War.

How interesting that the confluence of these factors has permanently closed the window to the two-state solution, precipitating, if you will, a "final solution" to the Gaza dilemma.

It's not a confluence of factors, it's a choice. The Israeli Left would probably be happy to let terror attacks and Hamas continue for their own purposes.

Again, just because someone could benefit doesn't mean the entire organization exists at the sole behest of the beneficiary.
