The head of the International Tennis Federation had "no second thoughts" about carrying on with the Davis Cup final and is confident every possible precaution has been taken to make it a safe event.
The clash between Belgium and Great Britain in Ghent, starting on Friday at the Flanders Expo, had appeared in some doubt after nearby Brussels raised its terror alert to the highest level last weekend.
Transport and schools were shut and sporting events cancelled while soldiers patrolled the streets because of the "serious and imminent" threat of a Paris style attack.
The hunt for individuals believed to be connected to the Paris attacks goes on in the Brussels area and, although schools and the metro system were back open on Wednesday, the alert level will remain the same for the rest of the week.
Some British fans have already decided against travelling but ITF president David Haggerty has been reassured by what he has seen in Ghent.
He told Press Association Sport: " We want to make sure the players are safe, fans are safe, staff, everybody that's here.
"It is very serious. We have multiple meetings each day. I'm very fortunate that I have great staff that are on top of this on an hourly basis. They bring me in a couple of times a day to keep me aware of what's going on.
"It's consumed more of each day than you would want, and it's important to communicate with both teams so they know what's developing as well.
"From my personal experience of taking the Eurostar, coming into Lille, travelling by car here, having lunch in town, walking around and seeing the sights, I feel very comfortable.
"It's a personal decision people have to make but I have no second thoughts about what we're doing and going on with the event with everything I've seen today.
"I'm sure there have been cancellations but at the same time there are also people that are looking for tickets so it might be a chance for them to come. I think we'll have a full stadium of 13,000 screaming fans pulling for their team."
Haggerty, a 58-year-old from the United States who only took up the role in September, denied the event had ever been close to being called off.
He said: "We've been following guidance and seeing what develops. At one point someone said, 'When are you going to make a decision?' and my point was, 'We make a decision when it's time to make a decision'. We're following all the guidance and we'll continue to do so.
"We've taken so many steps at the stadium to make sure we have the best plan in place. The city seems very nice. Walking around the streets people seem to be calm and going about their business, which is really what the world should be."
Security worries delayed the British team's arrival by 24 hours. Instead of flying to Brussels on Sunday, they chartered a private jet to Flanders Airport on Monday.
That in turn persuaded captain Leon Smith against making on early call on whether Kyle Edmund or James Ward would be his second singles player alongside Andy Murray.
Ward had a lengthy practice with Murray on Wednesday after the Scot had hit with Edmund on Monday and Tuesday, and the pair were set to find out their fate on Wednesday evening.
Smith must finalise his four-man team an hour before the draw on Thursday afternoon.
Coach Nick Weal said: " It's not going to be any different to the other ties. What normally happens is Wednesday evening we get together, coaches and medical team, and we talk about it then Leon will make his decision and tell the boys.
"Leon probably wanted to announce it a little bit earlier but the situation was all a little bit tense at the weekend when we didn't know whether we were coming or not. I think he's right to have delayed the decision."
