You are confusing the reason why those claims are somewhat believed.
In journalism, oftentimes sources can't stand for themselves due to requiring anonymity. So what backs that source isn't their personal details, it's the vetting the journalist has done.
This claim is NOT believable because it comes from a "US official", it's believed because it's vetted by a journalist from a publication the person deems trustworthy.
Not an expert, but that sounds like something a "state sponsor of terrorism" might do. >

The story sounds a lot like state sponsored propaganda >

White supremacist recently planed a drone bombing in Iceland.
Wanted to kill politicians. 
Thanks to interpol it was stopped in the planing phase. >

Not saying this to be an asshole, but want to educate. It is “planned” and “planning” with two n letters. :) >

Typos hapen. >

its amusing that Russia thinks that the free world is just going to balk in the face of terrorism and genocide,  
newsflash, angry vatniks. You aren't the only one with big scary weapons. >

i mean, look at the US here, we aren’t really treating terrorists with the same zeal that we did in 2001… and they’re on our own soil! >

They're inside the house ... of representatives >

Where there’s smoke…there’s facists >

If they're doing it in Spain, they're doing it in every western country. Like the electric grid attacks in NC and the northwest. >

THIS.
We know who they are, and we know exactly what they’re doing with these power grid attacks… It’s weird that the “deep state“ that’s soooo out to get them has not used this or anything shy of this as a pretext to scoop these terroristic fucks up. >

Russia has been at war with us for the last 10 years.
And people are only now beginning to wake up. >

Russia started its cyber war against the west the second their first modem was plugged in. >

Russian nazis are operating in the US too.  They did a bunch of $ shifting to the GOP via the NRA prior to the 2016 election in the US.  The gop is laden with demented nazis that love Putin and his ugly countrymen. >

I mean isn’t the founder of Vagner Group a Bonafide Neo Nazi bastard? >

He has nazi tattoos.  Yes. There really isn't another reasonable explanation. >

Oh, look: the UK conservatives like him too! >

It’s weird how these guys seem to be so sniper-proof… >

They are everywhere >

So when is the US Government going to acknowledge that white supremacist organizations are terrorist organizations and treat them as such? >

The FBI has been infiltrating and spying on them for decades. >

In other news, Spain is open to sending Leopard 2s to Ukraine.
Russia keeps fucking around with Western governments, eventually he was going to find out. >

If 9/11 can trigger art 5, why not this? Russia delenda est. >

You know why >

Russian 'intelligence' agents. >

Spies were talking about spies right? >

CNN really reachin the definition of “white supremacist” I mean I know they’re not doing much in the US rn but wouldn’t “Spanish Nationalist” work? Or at least be more accurate?? >

Try reading the article before commenting >

Anonymous US officials said it, which means it's either true or false. >

A statement is either true or false?
Way to go out on a limb there, buddy. >

I just hate the way that, even after Iraq, the word of anonymous US officials is still treated by some as the Absolute Truth. Given the track record of such people and considering the monumentally disastrous consequences of blindly believing them, a lil skepticism is warranted.
edit: See? Some are already wondering why the claims of anonymous US officials isn't triggering NATO's Article 5, because the word of anonymous US officials is seen as the absolute  truth. We have learned absolutely nothing from Iraq.
