Security isn’t the only concern facing the 2014 Winter Olympic Games that are about to commence in Sochi, Russia.

It appears the site is lacking in hotel space, streets and roads aren’t complete, the Olympic village where the athletes will stay need finishing.

Yet the Winter Games will go on, with opening ceremonies set to begin Friday night — after the skating and snowboarding events have begun.

Let’s flash back a decade to the start of the 2004 Summer Olympics in Athens.

I had the honor of visiting Athens three times prior to the start of those Olympics. The Greek press ministry invited journalists of Greek descent to visit the country of their ancestors. Being one such journalist, I got the invitation, so I went — in 2000, 2001 and 2003.

I recall vividly all the concerns leading up to the Athens Olympics. The venues wouldn’t be done. Security was huge concern there as well, given the Greeks’ infamously lax history of fighting terrorists, which is to say they did little to combat the scourge. Athens had a pitiful international airport, but by 2001 they had opened a gleaming new terminal outside of the city. They, too, had road and highway infrastructure concerns. They built a subway system, a new highway from the airport into the city, scrubbed the buildings of graffiti and spit-shined the ancient city.

Thus, they managed to complete preparation for the Olympics — on time. Yes, it was barely on time, but it was on time. One key was the Greeks’ decision to re-enlist powerhouse businesswoman Gianna Angelopoulous-Daskalaki, who put together Greece’s bid to play host to the Olympics. She stepped in to take command of the Olympic preparation. Believe me when I tell you that she is simply a force of nature. She got ‘er done.

The Greeks took some shortcuts to make sure the venues were suitable, such as not putting a roof over the swimming and diving facilities. It didn’t matter, given that the weather during that period was gorgeous.

To be sure, Greece paid a huge price to stage these Olympics. They went into enormous debt, which contributed to the collapse of the country’s economy just a few years after the Olympic flame was extinguished.

I bring all this up because the Russians, which were awarded the Winter Olympics in 2007, had promised to avoid all the troubles that bedeviled the Greeks. They vowed to spend whatever it took to ensure complete safety and a completed venue in time for the athletes’ arrival.

Well, now we’re hearing about the threat of bombs planted in tubes of toothpaste and the aforementioned incomplete road and highway construction and the lack of lodging for the thousands of tourists pouring into the Black Sea resort city.

That big old Russian machine needs some repair, it seems, especially in light of little ol’ Greece being able to stage an even bigger event than the one that’s about to get under way.

I remain hopeful that the Russian “Ring of Steel” will head off any terrorist attacks during these Olympics. The rest of it remains dicey. Let’s wish them all the best.
