Well, let's hope Trump wouldn't nuke anybody for saying his hands are small. But his incredible thin skin and demonstrated vulnerable ego is hardly an asset in diplomatic or military matters...

Again.

The US system is not that fragile. It's made to be able to deal with presidents smart or dumb.

I see no evidence that Trump should be any more dangerous than Bush or Clinton. He might say more outrageous things than even Bush to the international community but his rhetorics isn's his politics and he can't just send nuclear bombs at whomever he wants.

I'm not aware of any such checks or balances which would prevent a president from launching a military attack when there is at least the faint notion of a threat. He certainly doesn't need any parliamentary approval for the first strike and he is commander in chief of the armed forces. The only hope is that the military would refuse stupid orders.

I also don't see why anyone would want a thin-skinned man child in charge of the only superpower in the world. Being in the center of at least one pretty strong fraud case doesn't help either. The argument "he just says stupid things all the time, but he will be presidential and wise when he is president" doesn't even begin to make sense to me.

Well then you should read a little up on it.

The president will need permission to declare war.

Trump can in theory command the nukes to be fired without declaring war but this only works if there isn't any political opposition agains his case (i.e. it would be considered unpatriotic to disagree with his decision)

Given the general dislike for Trump there will be plenty of dissent if he decided to just send nuclear bombs left and right. The military would overthrow him pretty quickly.

So yes there are checks and balances and in the case of Trump they would make sure that he followed protocol.

You dislike him so your analysis of why he would be thin skinned has little value here too.

I have no personal interest in this as I can't vote, however I am not afraid of him more than Hillary (who is a known Hawk)

I don't believe he would launch nukes against someone. I don't believe that his staff would necessarily stop him, either. As far as I know nobody would be legally allowed to stop him. Even more so in the case of small scale military actions, like drone strikes or the bin Laden raid. Declarations of war are overrated.

Trump's thin skin is a proven fact. He still isn't over the jokes over his small hands. He felt the need to defend his penis size in a presidential campaign. He attacks voters at his own events. He verbally insulted almost all minority groups. His default reaction to any criticism is to personally insult the critic.
