Savings

quoting : "Poor Linkara =( He never gets to use his cool things before an evil robot takes them over".

He don't have the budget for it.

quoting : "Ignoring an intruder alert on a ship capable of destroying a planet isn't a good idea when the intruder might... I don't know... find the 'fire' button very quickly"

Our Hero ladies and gentlemen, a sample of Starfleet finest, only Khan could be more obsessed than him with the task ahead to ignore the obvious danger.

Quoting the first line from the Battle in the Mutara Nebula :

 [hailing Khan] "This is Admiral Kirk. We tried it once your way, Khan, are you ready for a rematch? Khan...? I'm laughing at the "superior intellect."

And as everybody knows, there he goes, boldly foll, facing off his certain doom.

And quoting Khan about the planetary explosion matter :

Khan: [shouts] THIS IS CETI ALPHA FIVE! Ceti Alpha Six exploded six months after we were left here. The shock shifted the orbit of this planet and everything was laid waste.

Okay, so in this case Starfleet cartography can argue that at the moment of the U.S.S. Reliant's arrival Alpha Ceti V was in the planetary path were Alpha Ceti VI was supposed to be and since Alpha Ceti V was supposed to be a M-Class planet the wasteland they find at the surface could not be the same planet because the Reliant's crewmen never bother to check the the cartographic and astronomic data banks to see if the stellar system match what they saw.

Therefore we can conclude and point the fact the Starfleet Academy gradutes are stupid in the 23rd Century and that was the true fact behind why Captain Kirk and the Enterprise original crew were IRREPLECEABLE.

Further evidences of stupidity after that Era are : Captain Picard and the Federation/Cardassian Treaties, Captain Janeway promotion to Admiral after commit several crimes against humanity and all sentient beings in general, Promote a Schizophrenic Hobo as Captain of the allegedly first starship called Enterprise in the 22nd Century and back Atop the Fourth Wall keep a compulsive comic book reader obsessed with bad comics who supposedly burn a few in charge of what can only be considered as a weapon of mass destruction in orbit of the planet Earth and that never goes anywhere else or even can landing on the planet.

Jesus, the man not even have a crew: just a robot, an artificial intelligence and a willing capable photogenic girlfriend who is never allowed to do anything else than be the proverbial helpless damsel in distress, again "OUR HERO LADIES AND GENTLEMAN, gentleman-feminist extraordinaire".

Well at least in his defense Linkara is a 23rd Century graduate so could be worst...hey wait a minute, it is worst.

Here, the Q-Continuum is prosecuting you Mr. Lewis Lovhaug a.k.a. Linkara for indulcing a mentally unbalanced universal supreme entity into suicide and so be responsible for it's murder.

Please if you survive the impending peril please proceed into the Celestial Temple of the Bajoran Prophets and face the charges against you, the prosecution already contact Captain Benjamin "Don't F@#k With" The Sisko to be your defense attorney but in case he can't be available for any reason the Q-Continuum will be more than happy to provide "Any" sentient being available to defend you, and we really mean "ANY".

Oh yes, about the planetary shifting : how do you scourge the planet and shift it's orbit without killing everybody in it in a matter of years instead of days ?

The accusation/defense/whatever rests.
