Raikkonen held off his Finnish compatriot Valteri Bottas to finish third despite a ten-second time penalty after admitting culpability in his collision with Hamilton.
Vettel said after the race that it was "silly" to think that either incident had been deliberate, pointing out that he had damaged his own race prospects in the collision in France. Ferrari now lead the constructors' standings by 20 points, proving their greater consistency as a team over 10 of the 21 season races so far.
The Englishman was quoted by Silver Arrows boss Toto Wolff who said on Sunday night: "To put it in James Allison's words, this is either deliberate or incompetence". Hamilton was hit early in the race, before recovering to finish second.
"What we need to discuss among all of us is if certain incidents occur and they have a massive outcome in terms of what's happening maybe around the race win and what the consequences would be, that's a different story".More news: Gal Gadot visits Virginia children's hospital in 'Wonder Woman' costume
Hamilton has promised he will "not give up" in what he describes as the "most intense battle we've probably all had" after the disappointment of not winning his home British Grand Prix.
Hamilton was seething was the race at Silverstone and suggested that Ferrari were implementing some "interesting tactics" during a race. "I had the advantage of the tyres, but it was not easy to find a way through".
With Scuderia Ferrari driver Vettel in front, Mercedes chose to do the opposite of what Vettel did - ultimately choosing to leave him out, giving him track position but on older, slower tyres. What's more, Mercedes had taken great pleasure in dominating on Italian soil at Monza in recent years - a track where Ferrari's victory drought dates back to 2010 - and this was seen as payback.
"The mind-set we have tried to create in the team is that failure is allowed", Wolff, 46, added.

"It was really hurting yesterday, this morning he got a lot of treatment and to be honest before the race I was really very concerned about him".
"We saw blistering last week in Austria, so keeping the tyres in good condition is going to be the key tomorrow given the high temperatures".
"The final move, obviously I was able to surprise him so I think he thought that I won't dare [go on] the inside and the braking zone was coming quite fast. My view, I did the best that I could, but there seems to be opposite looks of what I'm doing unfortunately".
