Skippy you got Free Antarctica vs. Samoa
Okay, after a bit of thought and some research, here's a off-the-wall scenario.
In 1994, for a final tune-up match before the Rugby World Cup, the Samoan rugby team traveled to Free Antartica. Tensions between Free Antartica and Samoa had been on a slight downturn after a large number of Samoan citizens were deported from Free Antartica. On November 20, 1994, eight members of the Samoan rugby team were killed after Antartican security forces stormed the hotel where they were staying after discovering evidence that the hotel was a front for a terrorist organization. In the aftermath of the slayings, three Samoan citizens attacked an Antartican on the streets of Tuasivi. Both governments demanded reparations and an official apology, but as both governments viewed the other as being in the wrong (the attack in Tuasivi occured before news of the slaying in Cape Murdo), tensions escalated. Two weeks later, a small group of Samoans attacked the Antartican embassy in Apia. After the attack, Antartica revoked all Samoan residence cards. Samoa then declared war on Antartica, but no military actions were untaken after the United Nations, Australia, and New Zealand were able to defuse the situation through a combination of threats of a trade embargo and a offer of aid. The 3 hour war ended with neither side actually gaining anything, and in fact, the Free Antartican President was impeached two months later, in part because of the damage to the economy from the loss of the Samoan workers.
