Hallgrimsson's side drew 1-1 with Israel in Serbia to conclude a four-game international window Republic of Ireland manager Heimir Hallgrimsson could only say he was "delighted" this most trying of international windows is over and hopes "no national team to go through what we have gone through over the last two weeks".
With four games played - just one on Irish soil - and about 5,000 miles travelled, Sunday's behind-closed-doors 1-1 draw against Israel in the Serbian town of Backa Topola brought the curtain down on two weeks that have taken their toll.
That his side took the field against Israel this week, and in last week's 3-0 victory in Debrecen, came under scrutiny and fire with the pressure group Irish Sport for Palestine's 'Stop The Game' campaign for a boycott because of the Israel-Gaza war.
That pressure ramped up before last Sunday's victory in Hungary with goalkeeper Gavin Bazunu making himself unavailable for those fixtures because he felt "it would be wrong to participate".
A vote held between the remaining players on whether to procced with the Israel games featured on a chaotic day. On the eve of Sunday's match, Hallgrimsson's news conference was cut short when an Israeli reporter made accusations that some Irish players made racist comments in their victory last week.
Those claims have been strenuously denied by the Football Association of Ireland, which had launched its own investigation into racist abuse directed towards their own players by some Israel fans in Debrecen.
