In The Name of Allah, The Most Merciful, The Bestower of Mercy.

Allah [The Exalted] stated about Prophet Musa [peace be upon him] when he accidently killed a person after a man from Bani Israel sought his assistance:

فَأَصْبَحَ فِى ٱلْمَدِينَةِ خَآئِفًا يَتَرَقَّبُ فَإِذَا ٱلَّذِى ٱسْتَنصَرَهُۥ بِٱلْأَمْسِ يَسْتَصْرِخُهُۥ قَالَ لَهُۥ مُوسَىٰٓ إِنَّكَ لَغَوِىٌّ مُّبِينٌ

So he (Musa) became afraid, looking about in the city (waiting as to what would happen to him due to killing a man accidentally), when behold, the man who had sought his help the day before, called for his help (again). Musa said to him: “Verily, you are a plain misleader!” [Surah Al-Qasas Ayah 18]

So, Musa [peace be upon him] said to him: [قَالَ لَهُۥ مُوسَىٰٓ إِنَّكَ لَغَوِىٌّ مُّبِينٌ – Verily, you are a plain misleader]. Imaam Ibn Al-Jawzi [may Allah have mercy upon him] stated one of the meanings of this statement in Zaadul Maseer Fee Ilm at-Tafseer as follows: “You are one misled in fighting someone whose evil you cannot repel from yourself”.

Imam Muhammad Ibn Saalih Al-Uthaymeen [may Allah have mercy upon him] said: “It is obligatory for Muslims to perform Jihaad in the path of Allah, but let it be known that jihad has conditions. One of its conditions is to have the ability (to do so). If the Muslims are unable to do it, then indeed, Allah [The Exalted] has not made it binding on them (to do so) due to His statement: [لَا يُكَلِّفُ اللَّهُ نَفْسًا إِلَّا وُسْعَهَا – Allah does not place an obligation on a soul (i.e. a person) beyond their capability]. And that is because the Prophet[ peace and blessings of Allah be upon him] was not commanded to fight except when he had a state with the apparatus of government, strength, and force to be reckoned with. It is not common sense and wisdom that we fight whilst not being able to do so because this means that our enemy will overpower us until he destroys us. For example, if a man departed with his sword, dagger, and spear with another man with missiles, planes, and the like, and said, “I am fighting for the sake of Allah”, do we agree to this? We will not agree because what this means is that you have exposed yourself to the enemy. [Tafseer Surah Al-Baqarah. Ayah 244]

When Imam Al-Albaani [may Allah have mercy upon him] was asked about provoking the Zionists, he replied, “If your circumstances carry on in this manner, imagine, what will be the outcome? What will the Muslims be seeing and witnessing?! What will the Palestinians be massacred for? What will be the outcome (when) a Yahoodi is killed and in return tenfold of Palestinians are killed, thousands put in prison? Would this be a victory against the Yahood? This is not the (right) path, (which) actually the Muslims have – at present – wrongly identified as the (correct) way of Jihad”. [Silsilah Al-Hudaa Wan-Noor 317]

Al-Allaamah Saalih Al-Fawzaan [may Allah preserve him] stated: What is obligated to us is that we reflect, rectify our deviated affairs, and repent to Allah. That is because the Yahood have not gained the upper hand against us except due to our sins. Why is it that we do not hear anyone addressing and admonishing the Muslims, whilst saying to them, “What has happened to you is (nothing else), except due to turning away from the religion ordained by Allah and negligence in the affairs of the religion. Therefore, repent to Allah in order that Allah may aid you and avert the plot of the plotters from you”. We do not hear except insult, abuse, and supplication against the Yahood, but this should be substituted with supplicating to Allah to rectify the Muslims and to make them steadfast. Mention to the Muslims that they should repent and return to Allah, and rectify their religious (affairs) for the sake of Allah. This is the first obligation. As for supplicating against an oppressor, whether the Yahood or other than them, there is nothing wrong with this. It is legislated to supplicate against the one who oppresses you with the Shariah supplications that can be found in the Book (i.e. The Qur’an) and the Sunnah. However, before supplicating against them, you should supplicate to Allah to rectify the Muslims, make the Muslims steadfast in their Religion, and return them to the truth. Advise, address, and admonish (them) regarding Allah [i.e. obedience to Allaah]. This is what is obligatory. [Al-Ijaabaatul Muhimmah Fil Mashaakil Al-Mulimmah. page: 202. slightly paraphrased]

Read about Peace Treaties:

Are Treaties With The Jews, the State of ‘Israel’ and other Non-Muslims Permitted? Is it Allegiance? Is it Apostasy?

Also bear in mind that regardless of what is taking place in any other place, we are commanded to behave ourselves and not violate the honour, blood, and property of fellow citizens in the UK and other countries.

Finally, as for help given by the Muslim governments to our oppressed brothers and sisters in Palestine, this is well-known. Therefore, during every calamity, we wait for the senior scholars of the Ummah to direct us to the right methodology – the senior Salafi Scholars, such as Al-Allaamah Saalih Al-Fawzaan, Al-Allaamah Rabee Bin Haadi Al-Mad’khali, Al-Allaamah Abdul Muhsin Al-Abbaad….

We ask Allah
رَبَّنَا لَا تَجۡعَلۡنَا فِتۡنَةً۬ لِّلۡقَوۡمِ ٱلظَّـٰلِمِينَ
وَنَجِّنَا بِرَحۡمَتِكَ مِنَ ٱلۡقَوۡمِ ٱلۡكَـٰفِرِينَ

Our Lord! Make us not a trial for the folk who are Zalimun (polytheists and wrongdoing). And save us by Your Mercy from the disbelieving folk.
