What you posted is only partially true and has been debunked several times.
I’m not saying Bush wasn’t wonderful but things didn’t happen as you laid out.

Here is an update I posted at my blog.
UPDATE
Here's a contemporaneous report from Fox News about the visit.
Former President George W. Bush and his wife Laura secretly visited Fort Hood last night and spent "considerable time" consoling those who were wounded in Thursday's shooting spree, Fox News has learned.
The Bushes entered and departed the sprawling military facility in secret, having told the base commander they did not want press coverage of their visit, a source told Fox News.
The couple was described as "deeply concerned" about military families on Fort Hood after Army Maj. Nidal Malik Hasan allegedly opened fire on soldiers and civilians, killing 13 and wounding 38.
The Bushes, who have a 1,600-acre property known as Prairie Chapel Ranch less than 30 miles from Fort Hood in central Texas, spent between one and two hours visiting the wounded and their families.However, according to Snopes, some of the circumstances are misstated in the e-mail I posted. I can't seem to copy and paste from Snopes, but the substance of it is that President Bush did have a secret service escort, that he was not requested to leave Fort Hood and that President Obama also visited some of the wounded soldiers there our days later, on November 10th.
