We, as a civilization are standing upon dangerous ground. There are people here in the United States who are making a concerted effort to undermine our elected government by accusing them of the most horrible crime imaginable: mass murder of our own citizens for political purposes. Some people, with agendas that include undermining that same elected government for other purposes, have been largely quiet in denouncing that particular insanity. Presumably because it works in their favor in a way.
The problem is, that tactics like that can work in the other direction as well. Spain is now being wracked by a simmering conspiracy theory that the commuter train bombings in Madrid three days before the elections were actually a socialist coup.
Spain's two largest newspapers, El País and El Mundo, have launched into a fierce row over their reporting of investigations into the Islamist train bombings that killed 191 Madrid commuters two and a half years ago.
The outbreak of hostilities between the country's most influential dailies follows the publication in El Mundo of a series of interviews with a small-time Spanish crook accused of supplying the explosives used in the bombings.
In the interviews José Emilio Suárez claims the bombings hid what was effectively a coup d'etat that brought the Socialist government of prime minister José Luis Rodríguez Zapatero to power.
Mr Zapatero's Socialists won a national election three days after the Madrid bombings, ousting a People's party that had led in opinion polls published prior to the bombings. "I am the victim of a coup they have tried to hide behind a bunch of muslims," Mr Suárez said.
On Wednesday El País published part of a conversation between Mr Suárez and his parents - apparently recorded by authorities during a prison visit - which it claimed showed El Mundo had paid him.
Socialist-supporting El País accused El Mundo of "yellow" journalism and stirring up conspiracy theories, including the idea that Basque group Eta may have been involved in the attacks. El Mundo yesterday denied paying Mr Suárez and claimed El País had taken his words out of context.
In a widening of the media war, privately owned radio stations have taken sides. The conservative ABC newspaper, the third largest Madrid-based daily, has also attacked El Mundo.
El Mundo has long been a critic of El País's powerful owner, the pro-socialist media magnate Jesús de Polanco, who owns TV, radio and publishing interests.
The spat between the newspapers also reflected a continuing campaign by the People's party to cast doubt on the police investigation into the Madrid bombings.
The campaign has split the People's party itself, as those close to former prime minister José María Aznar keep the conspiracy theories bubbling while other senior figures complain this damages the party's chances of re-election.
"There are more shadows than there is light in this case," the former minister Eduardo Zaplana said in parliament on Wednesday, claiming evidence appeared to have been hidden or falsified.
The People's party mayor of Madrid, Alberto Ruiz-Gallardón, this week called on the party to leave the investigation to the police and courts and concentrate, instead, on criticising government policy.
What is happening in Spain is almost a mirror image of what is happening in this country. I warned a long time ago that the unprincipled and unbridled partisan attacks could cause unwanted consequences. If these tactics bring down the government, then the successor party can expect the exact same behavior in return until its mandate is overturned and its government driven from office. And on and on until the system collapses.
The sickness is spreading. A lust to drive the "enemy" from office has already put Mexico in a bad way. Now Spain is following. But make no mistake. They are following the lead of what they see happening here in the US. They see that hate, vitriol, false accusations and manufacturered scandals work at undermining public trust.
We live in an age of insanity. In the end, as I said a while back, we all fall down. Every one of us.
